Lava Lamps!

6/13/2014

0 Comments

 
We studied materials in science and learned that oil and water form an emulsion when you try to mix them. Their particles can only be mixed by adding an agent like washing up liquid, which breaks down the particles and allows the two substances to mix. We used this fact to make lava lamps using water, food colouring, oil and old bottles we found at home. The colours look great and we cant wait to add our mixing agent- alka seltzer tablets- to it to watch the liquids mix like a lava lamp!
