Experiment 5: Lava Lamp!

The Experiment


The Results

Cloudy water.  Then after a re-jig, slightly less cloudy water.  This did not go well.  But that's all part of science too.  We learn from our failures as well as our successes.

The Science

Apparently what's supposed to happen is the salt falls through the oil, takes a bit of food colouring and oil with it and then dissolves in the water, releasing the oil to float back to the surface and leaving a puff of colour.
