You need a Kool-Aid packet, sugar, club soda (we only had Sprite in the pantry, so we just used that) ice and a blender.
1 kool-aid packet any flavor
1/2 c Sugar
2 c club soda, separated
2 1/2 c ice
In a blender combine the packet, sugar and 1 cup of soda. Pulse until sugar is dissolved.
Add ice and blend until smooth.
Add the last cup of soda and blend until incorporated.
Pour into cups and freeze for 30 minutes. (We skipped this step and it was still cool and refreshing.)
When time is up add straws and slurp.
