At first sight, it looks like 5 ball bearings!\u003c\/span\u003e\u003cbr class=\"ng-scope\"\u003e\u003cbr class=\"ng-scope\"\u003e\u003cspan class=\"ng-scope\"\u003eVery 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.\u003c\/span\u003e\u003cbr class=\"ng-scope\"\u003e\u003cbr class=\"ng-scope\"\u003e\u003cspan class=\"ng-scope\"\u003eWhat happens if there are only three ball bearings?

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 Gizmo 2.0 - thank you Simon. I hope your students appreciate you as much as we do!\u003c\/span\u003e\u003cbr class=\"ng-scope\"\u003e\u003cbr class=\"ng-scope\"\u003e\u003cspan class=\"ng-scope\"\u003eCONTAINS MAGNETS.
