My daughter loves to help with the dishes. Every chance that she gets she jumps up on her safety stool and washes the dishes with me. She was washing a particularly greasy item the other day & was having a hard time getting it clean. We added more soap to her sponge & discussed how oil & water react with one another.
We have done simple experiments with oil & water before, but I thought this was a great opportunity to do one of our old favorites. Here’s how.
Find an old 20 oz water bottle. Tear off the label & filled the bottle about 3/4 of the way full with vegetable oil & then pour the water almost to the top. Leave enough space so that the mixture won’t overflow once the lava reaction occurs. You will see the separation between the oil & water in the bottle almost immediately.
Add a few drops of food coloring to the water & then insert sequins. We wanted to make a fall themed lava lamp, so we used fall colors for ours. Once the sequins settle, add a half a tablet of Alka Seltzer to the bottle to stir it all up.
My daughter was thrilled to watch the sequins dancing around. She added tablet after tablet of Alka Seltzer to our homemade lava lamp.
Our homemade lava lamps were fun & pretty to watch.
Thank you as always for stopping by. Please follow us on Facebook as well.
That’s a really fun project. Watching the bottle would be so mesmerizing and relaxing.
