The Olympics Games are here (well, in Beijing) and everyone’s watching and trying to guess who will win a medal. But, apparently, even the Olympics is a source of scientific inquiry, and not just for geeks. The “Speedo” controversy raises some interesting points about the effect of a swimsuit on the swimmer, and the effect [...]

I don’t know what about you, but I have a box I keep my change in. I’ve bene thinking for a while what I can do with that change – buy a boat, rent a jetski, get a trip on those cool X-Planes that go up to space, etc etc. Big plans for small money, [...]

This is a very straight forward demonstration about static electricity, and it is working so well, that it really is fun to do anywhere with a faucet (and a plastic comb..).

Notice: This experiment is incomplete, and unclear. There were several attempts to correctly state the situation, but at the moment, a new re-make is planned to explain exactly and thoroughly what is happening to create this phenomenon.

I am about to show you how to extract your own DNA from your own bodies in your own kitchen. Yourselves.

It’s aliiiiiiiiiive!

Water is dense. Alcohol is Dense. But they’re not the same density, no siree. They’re differently densed. Which means we can use that to our advantage. And we do, in this experiment.
Well, this is more of a “Show off your geektitude” physics trick that will amaze and enchant your buddies anywhere! Okay, well, maybe not [...]

It’s Goo! It’s Solid! It’s Goo! It’s Solid! It’s— both???
My mom always told me never to play with my food, but in this case, I think even she will agree to make an exception. Not only am I going to play with this food, you should too. It’s way too fun to pass on.

All super-thieves know that lasers go straight. It’s the tenet of their masterplan to jump over, crawl under and squeeze between those annoying laser beams around whatever-it-is they are interested in stealing. It can take them weeks to study the angles and train to spray dust over it so they can see them. Talented thieves.

You probably hear this every day, that weird phenomenon sounds makes when it whooshes you by quickly. In fact, the entire ‘whoosh’ effect – that ‘zzzzzzzzzzzhoooooooom!’ that seems all children are familiar with and use as a description for a passing car is a great hint that something is going on.
