I have started doing science experiments with my 3 year old. I've seen a lot of different things on Pinterest and one big thing that I have seen is using vinegar and baking soda to make fizzy bubbles. After seeing a lot of different experiments like this on Pinterest, I decided to give it a try.
I filled a 9x9 clear glass casserole dish with about 1/2 inch of baking soda. We added about 1/2 inch of vinegar in 3 different containers and added a different color with food coloring to each container.
We took a dropper (one that comes with baby medicine) and dripped different colors onto the baking soda. My son was amazed and thrilled at the fizzy bubbles!
Doing that entertained him for at least a half hour.
After he had covered the whole area I let him play in the mixture with a spoon and fork.
He was entertained for a total of about an hour and would have played in it longer if it wasn't time for dinner. Ever since he keeps asking to do it again!
Great rainy day activity or just a great activity to get a little well deserved quiet time!
