First, some prep...

How we did it:

I took off the cap and taped a piece of paper snugly around the mouth of the 2-liter bottle. Then I took off the piece of paper and snipped a cut almost all the way through, right above where the mouth would be, where the cardboard would sit to prevent the Mentos from falling in until the right time. I tied a piece of string to the piece of cardboard so it could be yanked out from a distance.



2 kosher Mentos (thank you Shari! She got them from the Rabbi who brought them from Israel!);
2 regular (treif, LOL) Mentos;
5 regular Mentos;
5 cinnamon Mentos.

Here we go!
