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

Dancing on Ice: Why do ice skaters fall over? With Suzanne Shaw and Matt Evers

Without good balance, figure skaters risk epic fails. Ross Exton of the Live Science Team speaks to Suzanne Shaw and Matt Evers, two of the stars of ITV’s Dancing on Ice 2014, and takes a look at a real human brain to discover what stops us from falling over.
