Gaussian Gun
Roll the loose ball bearing down the track. Then something unexpected happens...
Why is it called the Gaussian Gun? Well, no reason really, except that a friend of ours just christened it that, and the name seems to have stuck. It is really very simple, which is why we like it! A plastic channel supports the row of 4 ball bearings, and a spherical neodymium magnet. At first sight, it looks like 5 ball bearings!
Very slowly, you roll the loose ball bearing towards the magnet. As it approaches, it is pulled into the magnet very quickly, neodymium magnets are very strong. And as a result, rather like that Newton's Cradle executive toy we used to see a few years ago, the ball bearing at the other end shoots off at a surprisingly high velocity.
What happens if there are only three ball bearings? Two?
Our original version of this item used 2 cylindrical neodymium magnets. However we received an e-mail from Simon Poliakoff, who teachers physics here in the UK, suggested that the use of a spherical neodymium magnet made the demonstration much better, and certainly more enigmatic. So we sourced the spherical magnets, and can now offer you Gaussian Gun 2.0 - thank you Simon. I hope your students appreciate you as much as we do!
