It’s a wonder what you can do with some recyclable water bottles, oil, food coloring, water and Alka-Seltzer. The children from Room 3 had an opportunity to satisfy their curiosity by finding out what happens when you add alka-seltzer to a bottle filled with liquids and coloring. Expectations ranged from, “It’s going to explode!” to “Nothing is going to happen.” Despite the differences in their hypotheses, one thing was certain, they all loved the result!
P.S. If you want to create the bubbly/lava lamp effect, all you have to do is add another tablet of alka-seltzer!
