The British Skeleton Team – Sliding to Victory
How would you like to slide down a very steep and winding track of ice on something very similar to a tea tray at around 140km per hour? Yes, no, maybe. Well, there are people out there who can and do want to. And what’s more, they’re really rather good at it.
Alongside Bobsleigh and Luge, the Skeleton is one of three sliding sports that take place on artificially refrigerated ice tracks. It’s a really white knuckle experience as each skeleton athlete pushes their sled one handed away from the start before lying down with their face first as they travel the track, using their shoulders, knees and toes for steering.
Everything You Need to Know about Rosetta and Philae
There has been a lot of excitement about Rosetta and Philae lately, but what are they and why are they so interesting?
What are Rosetta and Philae?
Rosetta is a spacecraft built by the European Space Agency; its primary objective is to help understand the origins and evolution of our solar system. In order to do this it has spent the last decade travelling into deep space so that it can rendezvous with a comet. Philae is the lander that has descended to the surface of the comet in order to take measurements and readings.
What is a Stick Bomb?
11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.
If you are thinking ‘What?’ then watch the rest of his TEDx talk to find out what a ‘Stick bomb’ is and what makes them jump.
