Doe anyone have a bubble mixture recipe they know works rather then me spending loads on the bottles of bubbles at ELC? I have tried this before and it did n't work so can someone promise me they have used the recipe before and it works? Thanks
Funnily enough our pupils did a science experiment a while back called the "bubble challenge".
They found that the cheaper washing up liquids (but not the cheapest I think "morning sun" came out well) definitely made the best bubbles but a few drops of glycerine (but not too much as that makes them more unstable again) makes the bubbles stronger and last longer before they pop. They filled a paddling pool with the solutions and made an enormous cylindrical bubble with a hula hoop round a child.
