A good, inexpensive drink for VBS is a Lava Punch made with sherbert ice cream and 7-up (or any type of lemon-lime soda). Scoop sherbert with ice cream scoop into balls, into punch bowl, pour 2- 2 liters soda over it (about 2 - 2 liter per 1/2 gallon sherbert). Gently stir, leaving foam. Rainbow sherbert works best for lava like punch but Raspberry & Orange works also. It also works best when it sits for a little while (15 mins or so)
