Lava lamp experiments

This is an amazing science experiment for children and you probably already have the bits you need at home. It comes from the book 'Potions Class' (affiliate link) and we had an amazing time playing with it.

You will need

• Glass jar

• Vegetable oil

• Water

• Food colouring

• Glitter

• Effervescent tablet (Berrocca or other)

Make it

• Fill the jar 1/3 full of water

• Fill the remaining with vegetable oil

• Add in some drops of food colouring and glitter

• Drop in a tablet (we decided two made it more exciting!) and see what happens!
