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.

Very nice but beware of tangling nylon cords if used with too young of child. I recommend this for 8 yr old and up.
