you will need:
some small hands to mix together
850g of plain flour
320g of salt(don't worry – nobody will be eating it)
480ml of water
and 4 tablespoons of cooking oil
mix until smooth but not sloppy (you can vary the amount of water to obtain the right consistency). Place an empty half-litre drinks bottle -
we used a glass jar with a hole in the lid
six drops of washing-up liquid and two tablespoons of bicarbonate of soda.
get the camera ready! and gently start to pour vinegar into the bottle. Your family's volcano will erupt with a satisfyingly realistic flow of bright red carbon dioxide foam 'lava'.
Oooh fab, I'll have to do this with the kids! Looks brilliant!
