When I'm out of ideas for things the kids can do, even though they have a playroom and bedrooms full of toys, we make slime.
My kids and I like this recipe because the fluffy texture is so fun to play with. We make at least two batches, coloring them differently, then twist together. Hours of fun at my house, no joke!
2/3 cup Elmer's white glue
1/4 cup water
1/2 teaspoon baking soda
Liquid food coloring
2-3 cups shaving cream
2 tablespoons contact lens solution
Optional: Essential Oils
I bought the gallon size Elmer's Glue online because it is cheaper and we make a lot of slime at our house.
I definitely supervise this process, especially when adding food coloring. Bryce likes to add several drops of each color and it can be so saturated that his hands turn green.
Buy cheap foaming shaving cream.
The contact lens solution you buy needs to have boric acid and sodium borate in the ingredient list. I use the Equate brand.
I've added 3-5 drops of essential oils at several stages of making slime, and it doesn't seem to alter the texture.
First mix glue and water in a big bowl with a rubber spatula, then add baking soda. Mix well.
Add food coloring and mix. Note that adding white foaming shaving cream will lighten the color a lot.
Spray in the shaving cream and don't worry about measuring this, just eyeball it.
Once everything is mixed well and the bowl is scraped down, add the "activator" (contact lens solution) and continue to stir.
The slime will be very sticky at first, and that is normal. You can switch to kneading it with your hands, and it will really start to form into a nice blob of fluffy slime!
