Neat idea for a kid's birthday party, tie balloons to favor bags. They will be festive party decor, plus every kid wants to take home a balloon! maybe that way I don't forget to give the favors tobtge kids!
Laser Beam Challenge - Set up a laser obstacle course in a hallway with crepe paper. The crepe paper will tear if the kids bump into it, letting them know they weren't able to get through the course. For added fun, do this in the dark with glow sticks!
