chuck box design by lupinsea found at the Expedition Portal. Looks like a lightweight, compact and functional idea (there’s a video below showing how it is set up. I could not find any plans for this box)
Leave of Mountain Dew in bottle, add a tiny bit of baking soda and 3 caps of peroxide. Put the lid on and shake - walla homemade glow stick (bottle) solution. What a fun summer thing to do with the boys!
