I'd like to say I consider myself pretty smart when it comes to telling whether or not things on the internet are true or real but this time, I was duped. Anna needed to do a project for school that either has a chemical or physical change. She had to come up with 3 ideas, present them to her teacher and decide on one. The one she decided on was The Glowing Mountain Dew Bottle. Now, I'm no chemist so don't judge but it seemed to me that it was a good, simple experiment that she could do in a 4th grade science class. This is how it was "supposed" to work: You take 3/4 of the pop out of the bottle, add 1/8 tsp baking soda and 3 cap full's of peroxide to the remaining 1/4 of pop in the bottle, replace the lid, tighten, shake and bingo, it was supposed to glow. It didn't do anything of the sort. All it did was make the pop cloudy. I then looked at all the reviews of this experiment and ALL of them said it didn't work, duh, ya think I would have looked at them BEFORE she made it her project of choice. Neil also checked Snopes and it came up with a big fat FALSE. Oh well, happens to the best of us sometimes. Figured if I posted this, I could save a few of you some time and disappointment and go onto something else.
Neil to the rescue...instead we went with a Buoyancy and Density Experiment, that is tried and true. It's equally as simple. Here is how it works: You take that same plastic bottle, fill it up completely with water, take a liquid fast food sauce packet such as soy sauce, add it to the water bottle. It will float. Seal the bottle. Squeeze the center of the bottle hard, you will see the packet sink to the bottom. Release pressure and the packet floats to the top. Simply put, by squeezing the bottle, it makes the bubble in the packet get smaller and the entire packet more dense, so it sinks.
I've since found some other good one's that I looked up and saw that they worked equally well. So, don't get duped like me, read the reviews.
