If it's good clean fun you want then you can't get much cleaner than playing with stuff where the testing takes place in the bath. Make your own bath bombs and investigate the science of 'fizz'. The bath bomb kit comes with enough stuff to perform various tasks and experiments using balloons and other pieces of kit.

This kit might be an ideal way to get your kids interested in keeping clean. Just get them to play with this kit and the first thing they will want to do is try it out. The instruction booklet even details how you can do magic tricks and plenty of other activities to keep them amused for hours on end. They might even take more of an interest in thier science lessons, although we can't promise this!

Included in the kit is:
Fragrance
Glycerine
Stirring and packing sticks
Pipette and spoons
Cirtric Acid
Mould and sandpaper
Balloon tie and balloons
Liquid colour pigments
Gloves and goggles
Sodium bicarbonate and more!
