Fizzing mixture recipe

I created this recipe to add to things that need a little bit of help dissolving in the tub, but it's also the basis of bath bombs.

Ingredients

1 cup baking soda (get it here)

1/2 cup citric acid (get it here)

1/4 cup arrowroot powder (get it here)

Super simple, mix all ingredients together and have on hand for other recipes or turn into a bath bomb or sprinkle into a bath for a powdered fun fizz.
