1/2 cup baking soda ($1)
4 oz jar of Vaporizing chest rub ($1)
5 drops eucalyptus oil ($1)
ice cub tray ($1)
plastic disposable bowl and spoon
Jar with lid
Okay, so I got most of this at the Dollar Store and I only used 1/4 of the the cornstarch, baking soda and eucalyptus, only used one of the 2 ice cube trays. This DIY is super cheap maybe five dollars.
In your disposable bowl, mix (with your disposable spoon) cornstarch, half of your baking soda, vaporub, and add the 5 drops oil.
Take the remaining baking soda and dust the ice cube tray.
With the mixture, use your hands to make small balls press them into the ice cube tray.
Freeze them for a couple of hours.
Pop them out and place them in an airtight container till ready to use.
I used disposable mixing implements because eucalyptus absorbs in plastic. *If you have sensitive skin you might want to use glove for this as well.
