I have used a toilet paper roll or paper towel roll... just cut in multiple slits about 1" long in on one end and then slide that end over the end of the flashlight (the cuts allow the roll to be either expanded or compressed around the end of the flashlight)... then just place the other end against the air cell end of egg.Cool - thanks! I think I'll just use my fingers for now, and track down some foam, etc later ....I'm not patient enough to hunt for foam or washers after work today![]()
