Leuk voor op de camping 's avonds. Just fill up a plastic water battle with water and put a glow stick inside and put the lid on. do this with a couple bottles then have a competition. Would be such a fun camping or backyard activity.
Craft Stick Catapult - my awesome Cub Scout companion leader used this to teach Leave No Trace: need 7 sticks for outdoor code rules, and signature. Band 5 of the sticks, band 2 of the sticks. You rock, Kimberly P.
A marshmallow (or other thing) popper from Real Simple. Cut off the bottom of the cup, cut off the top of a balloon, put them together, and then sling pop things around. Add some pretty duct tape around the cup to hold the balloon on better.
