"For camping or late nights at the beach? Leave 1/4 of Mountain dew in bottle (just don't drink it all), add a tiny bit of baking soda and 3 caps of peroxide. Put the lid on and shake - voila! Homemade glow stick (bottle) solution."
Ah yes, the infamous glowing Mountain Dew pin. I've referred to it before in previous posts and have received a few people asking about it. It's not being pinned as much as it was some time back, but I still see it pinned a couple times a day in my feed. It's source is a Youtube video which can be seen here.
But can you mix a just a pinch of baking soda and a dash or two of peroxide and get glowing Dew?
No. It's a hoax. My honest guess as to how it was done after watching the video is that they added the same chemicals found in glow sticks to the bottle, and when the peroxide was added it caused the same reaction as it would if you 'break' a glow stick (remember - the glass insert in glowsticks contains peroxide as well!) it formed a reaction and volva! "Glowing Mountain Dew!"
I think one of the reasons this keeps getting pinned time after time, despite there even being a Snopes.com article about it, is this pin offers a little entertainment and horror. The horror that something people commonly drink could glow (and let's face it, Mountain Dew is already a pretty horrific shade of day-glo green) but also that this is something we could pull out at the beach, at a BBQ, at home and impress our friends and family with. But unless you plan on doing the same as they did in the video by adding glow stick chemicals, it's not going to glow, or impress anyone.
