On Monday the first day back at school. We went to the lab and made lava lamps in a test tube we filled the test tube with 1/4 of the tube with water and then the rest with oil and then we put 2 food colouring drops in the tube and waited till that setted and then put borroca in it and watched it fizz over the top and the food colour bubbles rise and then watch it go down.
IT WAS FUN!!!!!!!!!!!
