The item delivered was much smaller than indicated, the base was only 9cm x 8,5cm and the height was only 9cm. The principle of conservation of momentum was demonstrable and so will be adequate for its purpose. However I was disappointed with the size. This needs to be amended in the product description.

Always loved these. This one lasted about 3 weeks but not because the product is flawed, because our son was very rough with it and got it twisted up. The product itself is just fine.
