Science Geeks will love these…
Science comes up with a lot of awesome stuff, and you don’t need a Ph.D, a secret lab, or government funding to get your hands on some of the coolest discoveries. We’ve got a list of 11 mostly affordable gifts that are guaranteed to blow your mind, whether or not you’re a science geek.

s frozen smoke, Aerogel is the world’s lowest density solid, clocking in at 96% air. It’s basically just a gel made from silicon, except all the liquid has been taken out and replaced with gas instead. If you hold a small piece in your hand, it’s practically impossible to either see or feel, but if you poke it, it’s like styrofoam.
Aerogel isn’t just neat, it’s useful. It supports up to 4,000 times its own weight and can apparently withstand a direct blast from two pounds of dynamite. It’s also the best insulator in existence, which is why we don’t have Aerogel jackets: it works so well that people were complaining about overheating on Mt. Everest.

hrimp, algae, and bacteria, all swimming around in filtered seawater. Put it somewhere with some light, and this little ecosystem will chug along happily for years, no feeding or cleaning necessary, totally oblivious to the fact that the rest of the world exists outside.
EcoSpheres came out of research looking at ways to develop self-contained ecosystems for long duration space travel. They’re like little microcosms for the entire world, man. But ask yourself: are we the shrimp, or the algae?
3. Mars Rock
NASA has been trying to figure out how to get a sample of rock back from Mars for a while now. You can beat them to the punch and pick up a little piece of the red planet without having to travel a hundred million miles, by just taking ad
vantage of all the rocks Mars sends our way.
Every once in a while, a meteorite smashes into Mars hard enough to eject some rocks out into orbit around the sun. And every once in a while, one of these rocks lands on Earth. It doesn’t happen often, but it does happen, and whoever finds the meteorite is allowed to cut it up into bits and sell it to people who want to have their very own piece of another planet.

The existence of a shape with these properties was conjectured in 1995, but it took ten years for someone to figure out how to actually make one that worked. And then everyone was embarrassed when it turned out that turtles had evolved this same basic shape in their shells a long time ago, to make it easier for them to roll themselves back over if they get flipped.The Gömböc is a self-righting object, which means that no matter which way you put it down, it stands itself back up. It’s like a Weeble, except it doesn’t cheat by having a weight at the bottom, and it’s the only shape that can do this.

5. Violet Laser Pointer
It’s no longer geeky enough to have a red laser pointer, or a green laser pointer, or even a blue laser pointer. Keep moving up the spectrum until you get to violet, and you’ll find the new hotness at 405 nanometers.
So what’s next year’s new color going to be? It’s looking like orange, but they’re not quite what I’d call affordable yet. Something to look forward to for next year, especially if you’re going for your own personal laser rainbow. – Update, they are affordable now!
Gallium is a silvery metal with atomic number 31. It’s used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit. If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid.
While you probably shouldn’t lick your fingers after playing with it, gallium isn’t toxic and won’t make you crazy like mercury does. And if you get tired of it, you can melt it onto glass and make yourself a mirror.
By themselves, Miracle berries don’t taste like much. The reason to eat them is that they contain a chemical called miraculin that binds to the sweet taste receptors on your tongue, changing their shape and making them respond to sour and acidic foods.
The upshot of this effect is that some things you eat taste spectacularly different. Straight Tabasco sauce tastes like donut glaze. Guinness tastes like a chocolate malt. Goat cheese tastes like cheesecake. After about an hour of craziness, your taste buds go back to normal, no harm done.
8. DNA Genotyping
There’s nothing more personal than someone’s own DNA. And there are ways to give the gift DNA that won’t get you children or arrested. With just a little bit of spit, you can get an genotype analysis that will reveal fun insights about longevity, intelligence, susceptibility to diseases, and even food preferences.
While the technology hasn’t reached the point where you can affordably get a complete sequence of an entire genome, looking at specific markers is still good enough to suggest some things worth looking out for while spurring a lively nature versus nurture debate.

9. Klein Bottle
If you want to give a mathematician something to try to wrap their head around, a Klein bottle is a good place to start. A real Klein bottle is an object with no inside and no outside that can only exist in four dimensions. These glass models exist in three, which means that unlike the real thing, they can actually hold liquid.
The difference between the models and the real thing is that by adding an extra dimension, you can make it so that the neck of the bottle doesn’t actually intersect the side of the bottle. Take a couple aspirin and try to picture that in your head.

They’re cute! They’re fuzzy! They’re potentially deadly! All of the microbes, bacteria, and viruses that you know and love (or maybe not) are available in huggable forms about a million times larger than real life. In the picture are gonorrhea, syphilis, mono, and herpes.
These giant plushes are the perfect way to make the holidays even more awkward, when you present your friends with a variety of adorable STDs. Microbiologists, at least, will appreciate that they’re more or less anatomically correct, too.
Magnetic particles suspended in oil never looked so sexy. That’s all a ferrofluid is, and it looks pretty gross until you put it in close proximity to a magnet, at which point it grows spikes all over the place as the fluid flows out along magnetic force lines.
Ferrofluids are found in everything from speakers to hard drives, but it’s much more fun to play with when when you’ve got a puddle of it naked and out in the open.

Try the taste sensation that's sweeping the nation: Miracle Fruit Tablets. Like magic sour foods (like lemons) taste like the sweeties candy on Earth. What are Miracle Fruit Tablets? They come from sweet berries about the size of coffee beans containing an active molecule called miraculin which binds to the tongue's taste buds when the fruit is consumed. Miraculin acts as a sweetness inducer when it comes in contact with acids, causing sour foods to taste sweet, temporarily. This effect usually lasts between 30 minutes and 2 hours. Miracle Fruit tablets have been around for centuries. They were first discovered by a French exploration in the 1800's. We get these directly from the only source available in the United States--they are guaranteed to be fresh.
