Glow in the Dark Mountain Dew Materials
- 20-oz bottle of Mountain Dew™ (but any bottle will work)
- glowstick or lightstick
- scissors or wirecutters
- dishwashing liquid (I used Dawn™)
- hydrogen peroxide
- baking soda
- Pour out or drink all but a small volume of the soft drink (~1/4 inch). If your bottle is empty, add a little water.
- Add a squirt of dishwashing liquid.
- Use scissors or wirecutters to cut the glowstick. (I do not recommend using a steak knife, but if it's all you can find, it will work.)
- Empty the contents of the glowstick into the bottle. I used a pair of tiny inch-long sticks intended for use as earrings, so I just cut them in half and tossed them in the bottle. If the liquid won't flow you can snip the glowstick into pieces and just add the pieces to the bottle.
- Add 1-3 capfuls of hydrogen peroxide.
- Add a pinch of baking soda and immediately seal the bottle.
- Turn out the lights (if you haven't already) and vigorously shake the bottle.
- You probably guessed this, but I'll say it anyway... don't drink the contents of the bottle. Keep it out of reach of children or anyone else who might be tempted to drink the liquid.
- There's nothing special about Mountain Dew. In fact, you don't even need soda.
- You can make the bottle glow any color you like. Just use the appropriate color of glowstick.
- You don't absolutely need the peroxide or baking soda either. The project works if you add a little detergent and the contents of a broken glowstick to any near-empty 20-oz bottle.
- However, if you add the peroxide and baking soda, you get an immediate bright glow. Enjoy the glow while you can because the chemiluminescence reaction proceeds rapidly. If you use peroxide you will notice the light starting to fade within about half a minute.
