Alcohol rocket
Here you can see the ignition of ethanol vapour in a bottle. The wave of combustion travels up the length of the rocket, the rapidly expanding gas increases the pressure, and the resulting propulsion sends it flying! Find out how to make a rocket in this video: http://youtu.be/xGrzjikAA5U

Memory Metal is a substance which can ‘remember’ pre-determined shape based on it’s temperature. When it’s cold it’s malleable, when hot it’s rigid. This nickel-titanium alloy is used in satellites to unfurl solar panels since it’s more reliable than heavy cogs & gears. In this image you can see a coil of memory metal being placed into a beaker of boiling water. Watch the full video here: http://youtu.be/w12KvC4chBU

How do we know what the Sun is made of?

The Sun fuses hydrogen into helium. But it’s too dangerous to simply take a sample to look at, so just how do we know what it’s made of? David Judge of the Live Science Team uses a trick of the light to show you how.

ZeroN - Levitated Interaction Element of Awesomeness

When I was younger, I used to push two magnets together until I found that point where a bubble of repulsion formed between them. With the weak magnets I had access to, I could always overpower the repulsive force and push them together, but I was amazed that there was some unseen magic acting upon two physical objects.

Like all of us, I later learned it was the forces of magnetism at work. The ZeroN project from Jinha Lee at MIT takes that to a whole new level.

By using computer-controlled magnetic field manipulations, a metal sphere is suspended in mid-air. Even more, it can be made to follow complex paths, “remembering” and repeating actions. If that somehow isn’t enough, just wait until he lights it up like an orbiting planet, and demonstrates Kepler’s Laws! Dude blew my mind!

It’s an experiment in challenging how we perceive natural patterns of motion, and whether computers, when combined with materials, can alter the way we interact with the world around us. Most of all, it’s AWESOME.

Tyrannosaurus rex bite force animated

In a new study published in UK journal Biology Letters, researchers at Liverpool University predict that a Tyrannosaurus rex’s bite is much stronger than previously thought. Researchers used laser scanners to digitize T. rex jaws and used computer models to reconstruct the jaw muscles of the T. rex and estimate its bite force. The study predicts T. rex had a bite force of 20,000 to 57,000 Newtons, equivalent to the force of a medium-sized elephant sitting down.
