Educational and fun, science boffins will love the pHantastic pHun experiment set from the Richard Hammond's Blast Lab range. This experiment set allows children to have fun with science through using everyday objects for experiments. Your child can go round the house testing household acids and bases with their own pH indicator papers and scale. They will be able to make egg shells disappear, clean coins or make a volcano. There is even a recipe for green eggs. All these amazing activities and experiments are explained in the instruction manual.
