I'm Ross, I'm a science presenter and video producer.



I mostly reblog stuff I think is awesome and post educational videos I've helped create.

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
