My daughter has been having a blast with these little experiments we started doing. Today we tried the make your own “lava lamp” activity I found on Pinterest of course. It was posted S.L. Smith Photography’s site. Kaitlyn insisted her bear had to watch the experiment too. Here they are adding the food coloring.
Then we added the alka seltzer tablet piece and voila.
I made the mistake of being cheap and not using as much oil as I should have so we didn’t get as much lava lamp action but she still had fun with it. Of course it just got better in her opinion when she dropped a larger piece in and it fizzed up and overflowed like a volcano. She had a great time and went through four alka seltzer tablets. It’s nice because I have no clue who bought them but they have been sitting in our closet for awhile now.
