Lava Lamps

This week, we’ve had fun doing a super cool science experiment, making our very own lava lamps! First, we had to fill the jars with some vegetable oil. We then picked which food colouring we would like to add to our lava lamps, before topping the jar up with water. And lastly, the secret ingredient – bicarbonate of soda. Once we added some of this, the mixture began fizzing and bubbling away! To finish our lava lamps off, and to make them light up properly, we placed them on top of our light table, which lit the magical mixture up and let us see all the moving bubbles properly. We all thought they were amazing!
