This is a good revision game, but you’ll probably only want to do this once a year… it’s pretty gross. You will need rubber gloves and lots of bubble gum. Divide kids into groups. Give each group a plate or flat dish and 3 or 4 packets of bubble gum. In 10 minutes each group needs to chew their bubble gum and make a sculpture out of the gum that relates to a Bible story or teaching point from past weeks (or that night). Warning: it smells pretty bad and rubber or latex gloves are a must!
Variation: Can do with play-doh for something less gross…
