We made a mess again today- creating volcanoes. This experiment always causes lots of screams of excitement!
Really easy to do at home :-
Best done outside or somewhere that is waterproof!!
Fill a cup 3/4 with warm water. Top up with vinegar ( any type), add a teaspoon of bicarbonate of soda and stand back!
You can add washing up liquid and/ or food colouring for more colour and foam! You can keep this going by adding more bicarbonate and vinegar.
