Bottle
You will need a 1 liter empty soda bottle. We used a 16 ounce bottle but it worked fine.
Alka-Seltzer
We used 1 tablet of Alka-Seltzer because it was a 16 ounce bottle but if you have a 1 liter bottle you will have to use 2 tablets.
Water
If you are going to use a 1 liter bottle put 3/4 cup of water if you are going to use the 16 ounce just divide it by 2.
Oils
You will need Canola Oil, or Vegetable Oil, or Motor Oil. (We used Castrol GTX)
