Have some good clean fun with the Wild Science Bath Bomb Factory! Experiment with all the ingredients and make your own scented Bath Bombs, a lava launch and much, much more! As well as being fantastic, fizzy and fascinating, the Bath Bomb Factory also teaches you about the science behind the ‘fizz’ and the changes that occur when materials are mixed. Follow the colour illustrated activity guide to see how it’s done! Just one of a range available from Interplay.
