Items Needed:
2 bowl to mix in (glass preferred; large & small)
mold (ice trays or designed shapes)
container with lid or plastic wrap (or both)
1 c baking soda
3/4 c citric acid powder
1/4 c corn starch
Essential oil/Fragrance oil
Liquid color
Mister bottle filled w/ water
Put all dry ingredients into large glass bowl. Break up any lumps. Mix thoroughly with fork/spoon or your hands. (complete mixing helps create great fizzies.)
Remove about 1/2 c & place in small bowl. Add in your color, do this a few drops at a time; writing down the amount of the color you prefer. Add in essential/fragrance oil, few drops at a time; writing down the amount to get the scent you prefer. Place the amount in the small bowl back into the larger bowl. Mix well.
Spritz the mixture LIGHTLY, over spraying will cause mixture to fizz! You only need enough mixture damp enough to hold together. Mix this with your hands, so you can judge the dampness. Only spray if ingredients won’t hold together.
Pack the mixture into a mold. Make sure to pack mixture down hard, adding more mixture (if needed). Pack one mold at a time.
Let mixture sit for a few minutes (no more than 5). Placing a piece of card board over mold, flip over. The solid fizzy will fall out onto the cardboard.
Let fizzies sit overnight before you touch or wrap, because they are very delicate at this point. Once the fizzies are dry, you can wrap them or place them in a container for later use.
I have made these in both silicon ice trays, as well as soap molds. Both came out amazing, the shapes make them a little more personal. But the cubes work just as well.
