The first one was easy.. we just needed plastic bottles, hydrogen peroxide, food coloring, yeast, dish soap and a funnel.
First, we mixed the yeast with some warm water and let it sit for a few minutes.
Meanwhile, we poured our peroxide into the plastic bottles and added some food coloring. Fischer chose red and Addison chose yellow. We also added a squirt of soap. I thought I took pictures of these two steps but I guess I didn't!
Then, it was time to add the yeast through the funnel. Slowly, the mixture started to foam and rise in the bottles! The kids had fun watching come up and out of the bottles and onto their trays. Eventually they got brave and touched it a little bit!
Our next experiment didn't go so well, but the kids still had fun. All we needed was food coloring, oil and warm water. Unfortunately all we had was olive oil and we were supposed to use vegetable oil. I thought I'd try anyway but it didn't work.
You mix some food coloring with the oil on a plate, then dump it into a jar of warm water.
The colors are supposed to separate again, sort of looking like fireworks in the jar. Ours just turned black. Oh well. :)
We will try this one again soon!
