As it was our first day back at school in a while, we thought it would be fun to get experimenting! Using water, oil, food colouring and Alka Seltzer tablets, we made our very own lava lamps. We made hypotheses about what would happen when we added the effervescent tab or when we added two different densities of liquid. There was the odd mishap and the Pouaka Room was decorated with a little more colour but in the end, we all came away with our own lamps to take home. Next time, we are going to look into adding UV paint to see if we can make it glow in the dark!
