This morning room 2 and room 4 created lava lamps.
At the start Mr Thurlow put oil and water in a glass beaker. We observed that the oil floated on the top of the water.
Then we added blue food colouring. The food colouring changed into tiny bubbles. Next, we added a magic white pill to the mixture. The bubbles began to dance in the mixture.
We thought the lava lamps were going to explode all over the table.
