The recipe below is based on the reaction of magnesium hydroxide (found milk of magnesia) with plain carbonated water. Here’s how to make your own:
- 1- liter bottle of fully carbonated unflavored seltzer water. Be sure the seltzer contains only water and carbon dioxide (CO2). Note: You can also use club soda with a small amount of added sodium.
- 3 tablespoons Milk of Magnesia (MoM)
- Chilla 1-liter bottle of fully carbonated unflavored seltzer water.
- Thoroughly shake the bottle of Milk of Magnesia. Measure and set aside 3 tablespoons.
- Carefully remove the chilled seltzer from the fridge. Make sure that you don’t shake or agitate it. To minimize the loss of CO2. Once the initial fizzing subsides, add the Milk of Magnesia.
- Replace the cap on the water bottle immediately. Shake the mixture vigorously for 30 seconds or until the liquid is cloudy.
- Set aside for approximately 30 minutes. You will notice the liquid will have cleared, and any un-dissolved magnesium hydroxide will have settled to the bottom of the bottle.
- Add lemon for taste and enjoy!
