Science Fun in Alder Class
In SESE we made lava lamps using water food coloring oil and Alka-seltzer tablets. We had so much fun. The two colors were green and blue. We filled a plastic bottle about a third of the way with water and the rest with oil. We added one drop of food coloring and then put one Alka-seltzer tablet in. We saw the tablet and water fizzing up and down.
