If you drop a chicken and an egg at the same time from a great height, which hits the ground first? Ross and Becky recreate Galileo’s famous Leaning Tower of Pisa experiment and investigate the physics behind it: http://youtu.be/bHsQ3V2AmEE
How can you use science to make a better paper airplane? Join Ross of the Live Science Team as he investigates how a wing works, the physics of flight and the science behind making a paper plane: http://youtu.be/AGzOOM0Pz98
How big is a hot air balloon? What’s it made from? Join Ross of the Live Science Team as he discovers how hot air balloons are made, shows you how to make one at home & meets one of the first pioneers of hot air ballooning
All you need to measure the speed of light is a microwave, a ruler & a bar of chocolate! To show you how to do this quantum kitchen experiment, here’s Ross & Nerys in this week’s portion of tasty science.
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
