Asking teachers to promote a playground toy is usually guaranteed to destroy its street cred. But that is the strategy for a science game that has already taken Sweden by storm.
"Magstix", a game involving magnets and metal ball-bearings, is set for a national tour of science classes. A professional actor will take a class, demonstrating scientific phenomena through the toy.
More than 250,000 Magstix sets have been sold in Sweden, where the game originates. The small magnetic sticks and ball-bearings are accompanied by a set of cards, suggesting games that can be played. They can be stood on end to create towers, or used in the traditional catching game of jacks.
