Have You Ever Made Glow-in-the-Dark Mountain Dew?
We did this when we were kids. It even scared some of the grown-ups. Take a bottle and put Mountain Dew in it to about a 1/4" depth, add a tiny bit of baking soda and 3 capfuls of hydrogen peroxide. Shake it and it glows. Spray it on the sidewalk to "paint". The kids will have a blast . . . we did! MAKE SURE THEY DON'T DRINK IT.
