fun with science

This weekend I went down to Newport News to visit with Emily and Greg. I had a great time seeing my two best friends. The weather was beautiful the whole time I was down there and Greg and I took full advantage by playing a little frisbee. Mostly the three of just just hung out in Emily's apartment or at the bar or a restaurant.

The most exciting part of the weekend was the science experiment we performed. On his way out here, Greg was listening to NPR and heard that putting Mentos inside of a two liter of soda makes the soda shoot out the top of bottle. Sounded like fun to us, so we gave it a try and it was worth it! We used Diet Coke because that supposedly produces the best results. Check out these pictures (you can click on the picture to see all four).

As you can see, the experiment was a big success. You just drop as many Mentos in at a time as you can and back up, no need to shake the bottle or anything. I don't understand the science behind this; all I know is that it's incredibly cool. Give it a try.

Perhaps you were blinded by science?

Next up, dry ice in a two liter!

The reason why Mentos work so well is two fold: Tiny pits on the surface of the candy and the weight of the candy. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. As soon as the Mentos hit the soda, bubbles form all over the surface of the candy. Couple this with the fact that the Mentos candies are heavy and sink to the bottom of the bottle and you've got a double-whammy. When all this gas is released, it literally pushes all of the liquid up and out of the bottle in an incredible soda blast.

Yea, it's wild, isn't it?

I did that back in April in front of my NPR friend and the next day NPR did a story on it! (Link)
