Get the chanichim to stand in a circle. The Madrich/a holds up a block of ice (make it by freezing water in an ice-cream container or similar.) and says three facts about her/him and then passes it to the next person. When the block of ice has been passed the whole way round and back to the Madrich/a, he or she will then throw the ice into the middle of the circle and a laminated note will be revealed reading "You have now broken the ice" Literally, an ice breaker.
