Today we did some awesome experiments.We did 3, but my favourite one was making a lava lamp.We made it by filling a small coke bottle a 1/4 full with water and filled it up to 3/4 with oil.Then we put in a dozen drops of food colouring.Then we got two berrocca tablets and broke them into 1/4's and put them in.Then we quickly put on the lid and walla! you have a lava lamp.
P.S. The lava lamp only lasts as long as the berrocca tablets bubble so you have it for 1 or 2 minutes.
