You will need:

• film containers (available from film developing stores)
• small plastic cups
• small measuring spoons
• baking soda
• vinegar
• red food colouring
• a plastic tray to hold everything on

 

What to do:

• tell children that they are going to be making a miniature 'volcano'
• encourage them to get a measuring spoon of baking soda and put it into a film container
• next, scoop a spoonful of vinegar from a plastic glass or cup and put it into another film container
• add a drop of food colouring to the vinegar
• now, slowly add a small measuring spoonful of vinegar mixture to the baking soda
• LOOK OUT! COOL!
• this activity is lots of fun and the children love making the 'volcano' erupt
• try and keep things in small amounts as accidents are inevitable
• keeping thing on a tray with edges helps contain the 'lava'
