Diet Cola and Mentos

Tonight for our family activity, we attempted the diet cola with Mentos experiment.  This is a fun thing to do with your family and the kids just love it!  All you need are plain Mentos and a 2-liter of diet cola (for some reason it has to be diet cola and not regular cola).  We decided to do a comparison of Diet Coke vs. a generic diet cola.



I quickly put 6 Mentos into each cola.  As you can see in the above picture, the resulting cola fountain went well beyond the height of our fence!  The experiment only leaves a little bit of cola left in the bottom of the bottle.  That means it leaves a big mess everywhere else, so we did it somewhere we don't mind getting all messy.

Here is the video of the event:

The only problem with our experiment is that we forgot to see which cola produced the higher fountain.  I guess we'll just have to do it again another night!
