Peppermint Float Punch

1 gallon vanilla ice cream, room temperature
Peppermint extract to taste
Green food coloring
3 to 4 (liter-size) bottles 7-Up

Mix ice cream with peppermint extract and green food coloring in a punch bowl. Add peppermint extract one drop at a time, as a little goes a long way. Add 7-Up to ice cream mixture.

NOTE: If you need more volume, just add more 7-Up to the punch.
