Make a Fizzy Bath Bomb

Use your chemistry to make a fizzy, scented bath bomb. Make them for yourself or give them as gifts!

2 T citric acid
2 T cornstarch
1/4 C baking soda
1/4 tsp fragrance oil
3-6 drops food color
3 T vegetable oil
Mixing Bowl
Waxed Paper
Small Cup or Bowl

Mix all dry ingrdients (citric acid, cornstarch, baking soda) in the bowl.
In a different bowl or a small cup, mix the vegetable oil, fragrance, and coloring together.
Slowly incorporate the oil mixture into the dry ingredients. Mix well.
Place 1" balls of the mixture on waxed paper. They will be semi-hard within 2-3 hours, but allow 24-48 for them to fully dry before storing them.
Store bath balls in a sealed container, away from moisture.
Add a few to the bath and enjoy! For gift giving, the balls may be placed in individual candy cups.
Either fragrance and/or coloring is optional.
Suggested vegetable oils include coconut oil, avocado oil, apricot kernel oil, sweet almond oil, or olive oil, although any emollient oil is good!
Use small molds to make three-dimensional fizzy bath shapes.
