- 1 bottle of coke, or any soft drink
- Shake the bottle of coke for 10 seconds, then place in the freezer for 3 1/2 - 4 hours. Keep checking back to make sure it hasn't completely frozen.
- Twist the bottle cap slightly and release some pressure, then tighten it up again. Do not completely unscrew the cap from the bottle.
- Flip the bottle upside down, then right side up. Wait 1-2 minutes, or until you see crystals beginning to form inside the bottle.
- Pour into a glass and enjoy!
