In room 2 we made lava lamps for science. We used water oil food dye and alka-seltzer tablets and a two litre bottle . First we put the water into the bottles, then added the oil. Then we put in food dye and an alka-seltzer tablet. Then we put cap on and swished it up. The tablet fizzed and the red food dye started to go up into the oil and then went back down. When the water touched the oil, it separated. It was great fun watching the bubbles go through the oil.
