Octopus escaping through a 1 inch hole

From the description: "Octopuses have an amazing ability to squeeze through tiny crevices, cracks and holes. My fall BIOS independent studies student, Raymond Deckel is investigating just how small a hole Octopus macropus can fit through as well as how long it takes them to squeeze through different sizes of holes. CAABS intern Rowena Day, NSF-REU intern Jared Kibele as well as teaching assistant Abel Valdivia help wrangle the 232 g octopus, Ray times it’s escape through a 1 inch hole while I shot video clips for later analysis. Location: Whalebone Bay, St. George’s, Bermuda. Dr. James B. Wood - BIOS The Cephalopod Page"

The 5 Ghz Project

Here's a 13 page article that explains what is happening. Briefly: Most microprocessors today run at somewhere between 2 and 3 GHz. By supercooling the processor with liquid nitrogen, they were able to roughly double its clock speed (and therefore its processing power). The only thing keeping mainstream chip manufacturers from increasing clock speed is the fact that, right now, a chip running that fast generates too much heat.

Baja trucks

These trucks are amazing - like any race car they have big engines, but the thing that makes them unique are the shock absorber systems. This article talks about the science of Baja trucks.

Supercooled water

There are a lot of videos like these on YouTube that show supercooled water. Here is what is happening. If you take very "clean" water (water with very few impurities, like bottled water) and have it inside a very "clean" container (like a plastic water bottle), and you lower its temperature slightly below freezing (like -6 or -7 degrees C), the water will sometimes supercool: It stays liquid even though it is below the freezing point. When you bump the water, a seed crystal forms and then the whole thing freezes in just a few seconds.

If it is -6 or -7 degrees C one night, you might try leaving several bottles of bottled water outside. Some of the bottles will freeze on their own, but normally a few will supercool and stay liquid.

How to make your own silly putty

OK, it's not really silly putty... but it is a putty-like substance:

So what is REAL silly putty like? According to this page, "During World War II, while looking for a cheap substitute for rubber, an engineer for General Electric, James Wright, accidentally developed Silly Putty®, now a famous toy.* Silly Putty is an organosiloxane polymer made from silicone oil and boric acid. Unlike home-made "play putty" it will not dry out, because it's not water based. Silly Putty has flexible molecules that, when 'smooshed' by fingers, slide over each other and cause the material to flow." See the page for lots more information and a second play putty recipe.
