VOLACANO!



Possibly the most rewarding thing you and your kids will ever do in the kitchen!
you will need:
A large bowl
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

in a large oven dish and mould your mixture around it to form the volcano's cone. Unscrew the cap and pour in warm water almost to the top. Add a splash of red food colouring ( we used paint and water didn't have any colouring)

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'.
