Intro: Clash Royale/of Clans Elixir Bottle
Make a game prop. Drinkable as long as you use water.
Step 1: Get a Large Corked Bottle
I got this bottle at target for 3 USD. A small flask can work too, but doesn't give as much feeling.
Step 2: Add Water
Simple as that.
Step 3: Food Coloring
Should be purple.
Step 4: Done
Add more if you like.
