Homemade Lava Lamp

Please leave a review

Build a homemade lava lamp and experiment with observing which items float and which sink.  Watch the video first, and then see what you'll need.  There are a few more unusual things on this list.  For example: Alka-Selzser, oil, water, food colouring, tin foil and a citrus fruit - oh - and a grown up.
