To see the effects in action we added some oil to the experiment. The oil made a layer on top of the water. We discussed why the water and oil didn't mix together. When the oil was settled we added some Alka Seltzer to the bottle and the effects were amazing. We made Lava Lamps!!!
The tablet let of a gas when it was mixed with the water. The gas then moved through the oil making it look like a Lava Lamp.
This was a fun experiment and the kids loved watching the bubbles of gas move through the oil.
Have a look at some of the pictures😃
