You will need (equipments)
We will have 4 groups of 5 students.Each group will need the following

Step2-Hydrogen peroxide can irritate skin and eyes,so put on those safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle
Step 3-Add 8 drops of your favourite food colouring into the bottle
Step 4 -Add about 1 tablespoon of liquid dishwashing soap into the bottle and swish and mix it.
Step 5-in a separate small cup,combine the warm water and the yeast together and mix for about 30 seconds
