"Real bombs are sad. Real bombs hurt. Real bombs are for making things break. Seed Bombs are happy. Seed Bombs heal. Seed Bombs are for making thing more beautiful. Seed Bombs are a simple way to add smiles to the face of the planet. We added a few more words to be more descriptive; we call them Seed Bombs Throw and Grow Plants, and you can learn more about them by reading the next chunk of words. Welcome to the next chunk of words. Each package of Seed Bombs Throw and Grow Plants comes with 6 bombs. Throw a bomb on some dirt and then wait. So long as it gets 4-5 hours of sunlight and some water, you'll have a patch of flowers or herbs in no time (fully bloomed or ready to be harvested in 6 weeks). The bomb part is made of clay and peat moss, so it protects the seeds while keeping them moist. Seed Bombs Throw and Grow Plants are a great way to spruce up almost any patch of ground. The Butterfly & Birds Bombs have a variety of flowers to attract things that fly, and the Tasty Herbs Bombs grow guys named Herb. Just kidding, they grow things like Parsley, Sage, Rosemary, and Basil! Even better, Seed Bombs Throw and Grow Plants make the perfect gift - why give someone flowers, when you can give them the means to make their own! Seed Bombs Throw and Grow Plants Just chuck a Seed Bomb at the earth, and (if given sunlight and water), it will grow plants (bloomed or harvestable) in about 6 weeks! Six bombs per package. Seeds are protected by clay and peat moss, which also helps absorb moisture. Each bomb covers about one square foot of earth in plants. Two flavors: Butterfly & Birds and Tasty Herbs. Butterfly & Bird Bombs grow a random mix of: Bachelor Button, Calendula, Chinese Forget-Me-Not, Lance-Leaved Coreopsis, Cosmos, Candy Tuft Mix, Larkspur, Rose Mallow, Siberian Wallflower, Alyssum, Plains Coreopsis, Toadflax, Black-Eyed Susan, African Daisy, Scarlet Flax, Godetia, Corn Poppy, Sulphur Cosmos, Blanketflower, Birds Eyes, Lupine, and Clasping Coneflower. Tasty Herb Bombs grow a mix of: Parsley, Basil, Oregano, Sage, Thyme, and Rosemary. Dimensions: each bomb is approx. a 1"" diameter (lumpy) sphere."

"This one-of-a-kind plant has lived on the Earth for over 290 million years and has the ability to “come back to life” (much like the undead) over and over again for hundreds of years! Simply place this seemingly dead ball of foliage in water and within hours it transforms into a vibrant green blood-sucking evergreen. Ok, we are kidding about the blood-sucking part. It's still amazing though! It's also great for lazy folks since you can forget to water your Dinosaur plant whenever you want! It will simply dry up and hibernate for up to fifty years and will spring to life every time it is given water. Some Interesting Tidbits about your Dinosaur Plant: During the Carboniferous period these plants used to grow over 120 feet tall (bigger than a T-rex) When dry it curls up into a tight ball so that the wind can easily roll it to a new location or cubicle, hopefully closer to moisture. Retains 3% of its water when it is dehydrated. Grows to be about 4"" Enjoys life so much it survived the Ice Age Kit includes: Live Dinosaur Plant (Selaginella Lepidophylla) Bag of genuine Volcanic Lava Rock Display Bowl"

How many times have you told your love that you would cut off an arm for them? Or give them a kidney or your own blood if they needed it to survive? Well, cutting off an arm is easy, but foolish. And giving blood or a kidney is noble, but could pose a big problem if you don't share the same blood type. What would happen, you wonder? It's very simple - your loved one's blood antibodies would bind to too many antigens in your donor blood causing the erythrocytes of your love to burst. That's right, their blood would explode! That's why we found this awesomely simple DIY Blood Type Test Kit. Just a little prick (no jokes, please), a few drops of blood, a little water, and the special card are all you need to find out what blood type you are. In just a few minutes, you'll have a card which will show you which antigens you have in your blood (which you can compare to a chart in the instructions to determine your blood type). And even better, this kit comes with a laminating sheet so you can carry the card in with you once it dries. Then, you will never not know what blood type you are, and you won't have to worry about your blood exploding. Click here for a brief step by step of the process. We shed our blood for these images...because we care.

Water is everywhere. It covers 71% of the Earth's surface and composes about 112% of the human body. Gaining control over water would be an awesome super power, but for now we are stuck with using science to master water. Good thing someone invented this Hydrodynamic Building Set. It makes science fun again. But this kit isn't a simple connect the dots - you have to do some thinking! Why? Read on! The instruction manual shows you how the girders connect, how to build the various tanks, and some rendered images of completed projects - but not step-by-step. Your entire model gets built up from the bottom of the carrying case, which acts as the water reservoir and also has a special footing to be the structure's foundation. Level by level, you build your support frame and add your tanks. Then connect all the tubes, add in the valves, and turn on the electric pump. If you've done it right, you'll have an awesome construction everyone will marvel at (a little food coloring helps). Fail and you're all wet - quite probably literally. And Kids: Build something with this kit for a Science Fair Project and you are guaranteed to win (this guarantee not guaranteed)!

"People often talk about the ""language of love"" and the ""hidden language and meaning of flowers and plants."" Well the time has come to cram these two languages into one easy-to-grow, polyglot plant. We give you, the I Love You Bean. It's very simple to show folks you love them with this plant. Read on, and find out why. You see, the I Love You Bean is just about the best gift you can give someone. When you do, tell them they only need to add water, sunlight, and love - just like the love your two hearts. Mushy, but effective. But here comes the best part: once the bean has sprouted and grown a little, your special friend will see the words ""I Love You"" written on the bean. And you will say it got there by the power of your love. You will score all sorts of romantic brownie points, and your energy expense for those points will be very minimal. You just have to purchase one (or more - you never know) of these I Love You Beans and let the love grow! I Love You Bean Ages: 3 and up (with adult supervision) Just add water, sun, and love, and you'll grow a unique bean - it has ""I Love You"" written on the bean! Sprouts in 3-5 days and shortly after the secret message appears. Includes: Sprouting dome, printed planter, Lima Bean seeds, planting mixture, and instructions & care information. Dimensions: 4"" x 4"" x 3.5"""

"We love our coffee and TeaEarlGreyHot and caffeinated hot chocolate, but if we had a nickel for every time we've spilled hot beverage on ourselves, we'd have at least five dollars. Who knew the walk from the kitchen back to our cubes would be so fraught with danger? The SpillNot mug holder will save you from spills with the magic of physics! Science FTW! Here's how it works: When you hold a cup of hot beverage, inertia keeps the liquid from moving. But when you walk, you create horizontal force, causing the side of the cup to press against the liquid, which then rises up and over the edge of the cup. The flexible loop handle of SpillNot cannot deliver a lateral acceleration to the saucer or the cup. As the handle moves horizontally, the saucer and cup swing up slightly in the opposite direction, balancing everything out so the liquid stays in the cup. When you are walking normally, the only force acting in a direction that is not parallel to the sides of the cup is the force of gravity. (Of course, if you apply a vertical force by jerking your hand around or dropping the SpillNot, all bets are off!) If the SpillNot is swung all the way around in a loop such that the cup is upside down at the top of the arc, the liquid does not pour out of the cup due to the force which acts in the opposite direction as gravity when the cup is at the top of the arc. (Note: Try this outside with plastic cups first. You need to experiment to get the right amount of speed in your swing.) Ready to carry your burning hot beverage around the office with confidence? Prepared to amaze your friends with crazy stunts starring physics? Get your own SpillNot and be the Mr. Wizard of the office. Product Specifications Genius invention that lets you carry a full cup without spilling it Put the cup on the base, lift and carry SpillNot by the strap You can even do tricks (with some practice, try outside first!) Excellent gift for: science teachers, people who spill drinks a lot Black plastic base with non-slip coaster and woven nylon strap Dimensions: 7.5"" tall, 6.25"" at widest point, 4.5"" wide base for mug"

We are certain you've seen these plasma balls before. They've been around ever since bad hair bands from the eighties. Recently they've become available in tech friendly USB versions so we've decided to put this classic on your must have list. Our only question really is why can't we have amazing, affordable, *NEW* desktop science toys invented in the twenty first century? Things like mini USB desktop wormholes, or keychain Schroedinger's kitten boxes? If you can't give us jetpacks, at least make some for our action figures... But ThinkGeek, How does the USB Plasma Ball Really Work? Glad you asked. A combination of interesting and fun gasses (like Argon) are first trapped inside a plastic sphere at relatively low pressures. An alternating current, at relatively high voltages (Hey, this is USB remember, so it can't get too crazy), are pumped into the sphere via an electrode in the center. This energy causes electrons to be stripped from the gasses,leaving in its wake some positively charged ions and a gorgeous gaseous and electrically conductive environment (aka Plasma). That high voltage served up through the electrode will now arc up through the plasma to the lower voltage edge of the plastic sphere (starting at the top where the temperature is greater). The arcs glow because they are hotter than the surrounding plasma. You can touch the plastic and the arcs will strongly congregate to your touch because you will be creating an even lower voltage jump from the electrode. All this made possible by the evil genius of Nikola Tesla, oh, and some science. Powered by an included USB cable, this desktop Plasma Ball is about stands about 6 inches high and includes an on/off switch. While it emits a very low current, it does so at a relatively high-voltage and so it does produce some EMF. Respect your plasma ball and it will respect you!

"General William Tecumseh Sherman has been called ""the first modern general."" Not only was he a tremendous military commander, he also was very fertile (8 kids . . . dang). He was admired by many, including one of his lieutenants (and naturalist) James Wolverton, who named a Giant Sequoia after him. And that Giant Sequoia is now the world's largest tree. And guess what? Maybe you can grow one to rival General Sherman. Just get yourself a Grow Your Own World's Largest Tree kit. Each Grow Your Own World's Largest Tree comes with everything you need (well, minus the sunlight and water) to grow your own Giant Sequoia. The cool thing about Giant Sequoias is that they grow well in almost every climate, so it will definitely grow for you (actually guaranteed by the manufacturer). And here's the kicker: General Sherman (the tree) is believed to be between 2,300 and 2,700 years old, which means the tree you grow with your Grow Your Own World's Largest Tree kit could be around for thousands of years. Pretty sweet. Grow Your Own World's Largest Tree Everything you need to grow your own Giant Sequoia (Sequoiadendron giganteum). Giant Sequoias are the world's largest living thing. Grows well in almost any climate. Guaranteed to grow (any issues, just contact manufacturer). Includes: seeds, growing medium, little stones, a mini-greenhouse, and detailed instructions. Dimensions: Well, the packaging measures: approx. 5.25"" tall, but the tree might grow (eventually) up to 300 feet tall!"

On a clear night, one has only to look up to realize how much wonder is still waiting for us in the universe. Out there, amongst the stars, are secrets and surprises beyond our wildest dreams. Well why not, while you're working on your own way of getting up there to the stars, bring the stars down to you? With the Star Theater Pro Home Planetarium it's as easy as a button press. The Star Theater Pro Home Planetarium is the coolest little optical star planetarium for the home you'll ever find. It will make you feel like you are sailing through the cosmos. Just turn it on in a dark room (aimed at your wall or ceiling) and begin gawping. You can set the stars to move (1 revolution per 10 minute period), so you actually feel like you're outside. You can set a nap timer (so the unit will shut off after 15, 30, or 60 minutes once you are asleep). Behold, the stars.

The intriguing design of this engine, invented and patented in 1816 by Dr. Robert Stirling, is still relevant today. Initially sought as a safer alternative to steam engines (whose boilers could explode), this engine never saw wide spread use because it was generally very heavy and required high temperatures. The principle of the engine is simple: an external heat source and heat sink create a temperature difference in a cylinder and the air inside expands and contracts, moving a piston and a crank shaft in a rotary motion. The energy source can be any source of heat or cold, including solar or even an open flame. The Stirling engine can be more efficient and quieter in comparison to the more familiar internal combustion engine. This Stirling Engine Kit is a truly unique gift for the person who thought they had everything - an engine that seemingly runs on air! But this engine can run on the heat coming from your hand. Please note that it is a kit and some assembly is required. Not suitable for children under 3 due to small parts. The instruction manual is available for download.

"At the inception of this product description, let's begin by saying we won't reference any movies. No movies with totems or tops or that guy from Critters 3. This has absolutely nothing to do with any of that. It's just a top that, once spun, will continue to spin for about a week. It uses magnets, and that's why we call it the Magnet Powered Spinning Top! Science-wise, it's actually pretty cool what's going on with the Magnet Powered Spinning Top. See, you get a spinning top with a radially oriented magnetic field and an associated base that houses a conductive coil. When the top spins past the center of the base, its changing magnetic field induces a current in the coil which momentarily opens the switch to the battery resulting in powering up the electromagnet. The electromagnet then delivers enough torque to the spinning top to allow it to speed up and spin away from the center. And because the electromagnet isn't always on, your Magnet Powered Spinning Top can spin for about a week - sometimes more! If it spins for a lot longer (like months or forever), well . . . maybe then you're trapped in a dream. Magnet Powered Spinning Top Spin the top and it will continue to spin for about a week - WITHOUT STOPPING! Kinda like the top totem in that movie everyone was talking about. Are you dreaming this? Actually, it uses a little electromagnet to pulse magnet magic out whenever the top goes through the center of the base. An easy way to amuse and impress everyone who passes your desk. Battery: 1 9-Volt (included). Dimensions: Top: 0.75"" diameter x 1"" tall. Base: 3.5"" diameter x 1.25"" tall."

"Our favorite beer to drink during the daytime is root beer. Why? Because it is flavorful, frothy, delicious, and won't get us fired. But sometimes we just don't find the root beer we crave.

"Oh. Hi. So. How are you holding up? BECAUSE I'M A POTATO! Some of our fondest memories from Portal 2 were of carrying PotatOS around the testing facility. We felt so close to her; it was almost like we were friends. Except we weren't, really. But we understand. Her days used to be easy. She tested. Nobody murdered her or put her in potato or fed her to birds. It was a pretty good life until we showed up. If you missed the children's Science Fair at Aperture Labs, no worries! We've packaged nearly everything you need in this handy PotatOS Science Kit. The kit even includes a miniature science fair poster with brand new content from Valve's writing team! Why ""nearly everything,"" you ask? You'll have to provide your own potato, but we're sure you have one nearby. Follow the directions and in minutes you'll turn a mild-mannered Russet potato into your very own PotatOS that lights up and will insult you, just like old times. Product Specifications Science kit to make your own PotatOS It really works! When assembled, PotatOS's light will illuminate & talk 17 audio clips from Portal 2 included Press a button on the PotatOS unit when you need to crush your ego Yellow light blinks when PotatOS speaks Package includes: 1 main PotatOS unit 2 tall wire guides 2 round head pins 3 rubber bands 6 U-shaped staples Instructions Miniature science fair poster Potato not included, so add that to your grocery list Click the details tab above to see what the PotatOS will say Cardboard science backdrop includes new material from Valve's writing team! Officially licensed Portal 2 collectible Batteries: CR2032 (included) Not a Toy. For ages 14+ Note: Do not eat the potato after using it for PotatOS. IMPORTANT NOTE PotatOS is a simulated science kit. It is not actually powered by the potato you supply. A single potato could not provide the voltage needed for LEDs and voice. An internal button-type battery provides power. However, PotatOS detects when it is connected to a potato giving the illusion of being powered by the potato. Gotcha? Good."

"Music boxes came to prominence in the 19th Century, but their history dates back a few hundred more years. You see, there was this bell ringing dude who got tired of all the hard work. So, he decided to engineer a device to make his life a little more hip. It was a cylinder with metal studs. Each stud (as the cylinder rotated) operated cams which rang the bells. Further research determined that the first song played on this new system was the theme to Super Mario Brothers! And so that's the first song we made when we got our hands on this awesome little kit (albeit with one note wrong to adjust the key). This music box kit is a bit more open source, though. There are no pins, but a strip of paper, which you punch yourself. That's right, you punch all your own songs! No more listening to ""Memory"" - it's time for Koji Kondo's greatest hits (the genius behind many of Mario's and Link's most memorable themes). We'd love to chat more, but it's time for us to compose a lullaby for Princess Peach. Click here to download a PDF blueprint of the Super Mario Brothers theme. 'Cause sharing is caring. DIY Music Box Kit In Action!"

Ornithopters are everywhere. But just in case you're thinking we're crazy, we'll list a few places you've seen these amazing flying devices. The 'thropters in Frank Herbert's Dune. The sidequests in Bioware's Jade Empire. The movies of Hayao Miyazaki. The Ornithopter card in Magic: The Gathering. The chimp-powered airplane in Madagascar 2. And our personal favorite, the half-ornithopter, half blimp that serves as the Ranger plane in Chip n'Dale Rescue Rangers. (Which probably tells you how old the monkey writing this description is...) Ready to bring a classic toy home to the digital generation? The Classic Ornithopter is a bright yellow birdie with colorful, tear-proof wings. Simply wind up his rubber band, align his tail, then toss him in the air to watch as he flaps his wings and flies up to 25 meters (about 82 feet) away. What's better than an afternoon where you can play with a flying toy and discuss Leonardo Da Vinci, Sir Isaac Newton, and the awesome science that is physics? Product Specifications WARNING: Choking hazard. Small parts. Not for children under 3 Recommended ages: 4+ with adult supervision Mechanical bird flies up to 25m (about 82 ft)by flapping its wings Classic toy for fans of birds, and or aviation Powered by a rubber band (one spare rubber band included) When you crank your ornithopter up, the rubber band stores up the energy that is used to power the tear-proof wings Directions: Pull the lever up under the right wing Hold bird upside down and crank the handle 50 times Lift the tail up (experiment with different tail angles) Press in switch under the right wing Once the wings begin to flap, lightly toss up and away. (Do not throw forward like a glider.)
