Forever blowing bubbles
A week of scientific testing - creating a fair test.
This week we have been creating the ultimate bubble mixture. We decided that the mixture that created the most bubbles was the best.
Our recipe is:
15ml of washing up liquid to
50ml of water.
We then investigated the affect of glycerine on bubble solution.
Our conclusion is that glycerine can make your bubbles last longer. You only really need 3 or 4 drops.
We ended our science sessions by challenging ourselves to make bubble caterpillars.
