Diet Coke and Mentos Experiment

This experiment is old news but I've always wanted to try it and now Grey is at the age where he could be involved.  Don't you love having a kid as an excuse to do fun stuff?

Grey charted the ingredients in his journal first.  Then we had some friends over.  I bought 4 of each so we could do it several times and everyone could have a turn.  I read that you could put a strip of tape on each side of a row of Mentos but that was really flimsy.  We had this tube that came with Glowsticks in it and it worked marvelously to hold the mentos vertically in a row and allow them to drop quickly into the 2 liter. 

1. Gather Materials: 2 liter of Diet Coke and a pack of mint Mentos.
2. Put Mentos in a tube. Place a piece of paper between the tube and the open 2 liter so that you can pull it out quickly allowing the Mentos to fall in.
3. Have someone hold the tube and someone pull the paper out.
4.  BACK UP!!!!! TAKE PICTURES!!!!
