As a scientist you can spot cool science in the world all around you every day!

Here we are collecting our Experiment Files on how to do some of our easier demonstrations for yourself at home or in the classroom. You can also find our latest YouTube videos where you can see how to do some simple experiments, learn about things such as dinosaurs, aliens or the Earth in archive talks from Crash, Bang, Squelch!, or meet our friendly demonstrators to find out what inspires us.
