Ingenious kit containing plastic granules which, when simply mixed with water, can be turned into bespoke bouncy balls. A mixture of up to five colours can be poured into one of the three supplied moulds (one large, spherical design and two small, irregularly shaped ones), immersed in water, and then split open after four minutes to reveal a superbly bouncy creation. There are ten sachets of granules included (two of each colour) so between four and ten balls can be made. 8
