While water is the most commonly used liquid to fill up a bong, there are several other options you can use to change up the smoking experience:

  1. Ice: Adding ice to your bong cools down the smoke and provides a smoother hit.
  2. Fruit juice: Filling your bong with fruit juice can add some flavor to your smoking experience. However, it’s important to note that sugar and other substances in fruit juice can cause residue buildup in your bong, so it’s important to clean it thoroughly after each use.
  3. Tea or coffee: Using tea or coffee instead of water can add some flavor to your smoke. However, it’s important to make sure the liquid is cool before using it in your bong, as hot liquids can cause the glass to crack.
  4. Alcohol: Some people use alcohol, such as vodka or whiskey, to fill their bong. However, this can be dangerous, as inhaling alcohol fumes can be harmful to your health. It can also be damaging to the glass, so it’s not recommended.

It’s important to note that while these alternatives can change the taste and texture of your smoke, they may not be the healthiest option. When using any liquid in your bong, make sure to clean it thoroughly to avoid buildup of bacteria and other harmful substances.
