You will need a large supply of "Lovehearts" to play this - the little Valentine's candy conversation hearts you see every around Valentine's Day - but it is a fun game which the kids will enjoy.
You will need:
At least two packs of sweets per player.
Each child starts with a collection of sweets in front of her. They should be spaced out evenly, flat on the table. At your signal, the kids build a tower of sweets while you time them. Time for 20-30 seconds. If your tower falls over, you are out.
Encourage the kids who are out to cheer on the remaining players. Keep playing until there are only 2 or 3 players left, then have a "final". The winner is the only one left standing when the other towers have fallen down.
