This week, we had some fun with making soap. I used to be very wary of using lye near small children, but decided to give it a shot with very, very careful supervision. The older girls had a blast and learned loads.
Making soap is a great way to work in some math and science. We talked about the chemical reaction that heats up the water when it’s mixed with lye, and also about the process of saponification.
I used a mix of coconut and palm oil, so the soap bars were ready to unmold pretty soon and popped right out of the cute little silicone molds the kids chose.
Those who don’t feel like using lye at all: you might want to try making soap jellies. It’s quick, easy, and super fun.
1/2 cup clear liquid soap
3/4 cup boiling water
1 packet of gelatin (about 1 tbsp)
A few drops of food coloring (optional)
Dissolve gelatin in boiling water, add soap and food coloring, and pour into molds. Allow about an hour to set. You will get squiggly jiggly bits of soap jelly that are very fun to use in bath. This activity will leave even the most stubborn bath refusers squeaky clean!
