Drink 3/4ths of a plastic 20 oz. bottle of Mountain Dew but leave the last 1/4 in the bottle. Add a pinch or two of baking soda and 3 caps of peroxide. Put the lid back on and then shake and voila... you have a homemade glow stick perfect for backyard fun, camping or the next PopCrush Alive After 5 in Downtown Billings! It looks more ghetto than the manufactured glow sticks in the photo above but that's half the fun!
