The very thing for running around in the sunshine after.
- 40ml cheap, runny washing up liquid (the thicker ones might be better for washing up, but they make smaller bubbles so…)
- 200ml water
- 10ml glycerine
- Mix these ingredients together well
- Test the mixture by creating a large bubble – bend a clean metal coat hanger into a roughly circular hoop and dip the hoop in the mixture and lift it out. A thin bubble film should be suspended in the hanger which, if you swing the hanger around in an exuberant circle, should make a big bubble.
- If no film forms on the hanger, add some more detergent and mix together again. If a good-sized bubble doesn appear when you swing around, add a little more glycerine.
Essentially you can make any amount with the proportions 4 parts detergent / 20 parts water / 1 part glycerine
