This week in Science 1st Class made exploding volcanoes!
If you want to try them at home you will need:
Cardboard, a small jar, a spoon, bicarbonate of soda, vinegar, food colouring and washing up liquid.
What to do:
Make a volcano shape out of cardboard. We cut out a circle with a slice missing and cellotaped it up leaving a hole in the top.
Put the jar in the middle of the hole and pour some vinegar, food colouring and washing up liquid into it. We placed our volcano on a tray in case it spilled out onto the table.
Add a spoon of bicarbonate of soda and stand back!
