Quality time with Kid3 looks like projects Mom wants to do anyway. We made bath bombs. While my usual mold is the ball that you get your pantyhose in, I sometimes use the little paper cups I keep in my bathroom for brushing my teeth. Last night Kid1 was being a teenager in the bathroom so we used little disposable horderve bowls.
8 oz. Baking Soda
4 oz. Citric Acid (I get it from Whole Foods. Sometimes with vitamins. Sometimes with canning supplies.)
4 oz. Corn Starch
2 oz. Epsom Salt
2 oz. Dead Sea Salt (I get the big bag next to the Epsom Salts at Walmart)
Separately, whisk together:
¾ teaspoon water
2 teaspoons essential oil (your choice, your scents)
2 ½ teaspoon almond oil (or olive)
A few drops of food coloring (going nuts will compromise how it clumps or if it reacts early)
Whisk the dry mixture while slowly pouring in the wet mixture. It should begin to clump together and hold its shape if you squeeze it. Too much liquid can start an early reaction and your bath bomb will bomb in your bowl.
Pack the mixture into your molds as tightly as you can. Let it sit for a few minutes before carefully removing them from the mold.
I like to line a fluffy towel with wax paper to cradle them, but paper towels work too. Let them sit and dry for at least a day before you use them.
Once dried, keep them in an air tight container, cellophane, or tissue.
