How to Make
First protect the area that you will be doing this experiment on or try it outside. Wear an apron or old clothes as the food colouring can stain.
- Fill a shallow bowl with a mixture of water and a generous amount of liquid soap and mix.
- Take your bottle and with the help of an adult cut the end off, leaving just the top half.
- Cut a square of fabric from the bag big enough to fit over the bottom of your bottle.
- Fix this onto your bottle with rubber bands.
- Take the lid of the bottle so you can blow into the top.
- Dip this into the soap mixture until the fabric is saturated.
- Remove this and let it drain a moment so that it’s not dripping wet, or your colours will run.
- Now paint the fabric with food colouring
- Then blow into the mouthpiece and you will see a foam rainbow appear.
