Here's a short tutorial how to make them:
1) Gather your supplies:
-Some kind of vacuum sealing machine (I used a FoodSaver vacuum sealer)
-Vacuum sealing bags/ pouches (I used these)
2) Fill the bag with your liquid of choice.
3) Add fillers of your choice.

4) Start vacuuming and sealing!
Now it's time to vacuum seal! I didn't let the FoodSaver vacuum out all of the air (I just stopped it and sealed it right before all of the air was out of the bag). Then I did a second seal for extra reinforcement! ;)
