Plama is cool little toy for your fridge: 12 magnetic shapes that can be put together to allow a marble to go through a course before landing into a small catcher at the end. The magnets' shape prevents the marble from falling off.
Plama may help to develop creativity and logical thinking. It can increase the understanding of two dimensional space and proportion. Using the outline of the shapes to build a well-functioning marble run is an easy way to focus on complex thinking.
