BluffBlocks by Emma Brix – wooden balancing blocks (3+)

From the outside, BluffBlocks look like ordinary wooden building blocks – yet already after the first stacking a surprise is revealed. Small mobile metal weights inside the blocks –depending on how they are stacked – will cause their center of gravity to shift and perform unforeseen movements. In this way, primary school aged children can get a feeling for physical laws in a playful way and construct small structures that artistically move back and forth. The BluffBlocks are produced in Germany’s magical toy-land Erzgebirge — an excellent, didactic fun for all physicists to be.
