Ghoulish Lemon Volcanoes

We didn’t do these Lemon volcanoes as a specific Halloween activity, but they are quite Halloween-ish. They look like some sort of witches cauldron bubbling away.

Make sure you follow my science board on Pinterest for more ideas. Don’t forget to save the pin for later.

For Lemon Volcanoes you will need:

  • Lemons
  • Knife (for adults only)
  • Food colouring
  • Bicarbonate of Soda
  • Washing Up Liquid
  • Craft Stick
  • Vinegar (optional)
  • Container

To prepare your lemon volcanoes cut the base of them so that they stand up. Then cut the top off to create a crater. Juice a second lemon and keep to the side in case it is needed.

I highly recommend putting the lemon in a big tray or container. This activity gets very messy.

Put a couple of drops of food colouring and washing up liquid into the lemon. Next add some bicarbonate of soda and use the craft stick to mix it in. The bicarbonate of soda and lemon should start to mix and cause a reaction.

Keep adding food colouring, washing up liquid, bicarbonate of soda, and lemon juice as needed. If you run out of extra lemon juice use vinegar instead.

YC and EC loved doing this experiment. In the end they gave up using their craft sticks and just stuck their hands in. EC did end up with hulk like hands for at 24 hours afterwards.

Even BB wanted to do one.
