Description:

Presenter puts Mentos candy into soda to create a soda fountain. This is a dramatic demonstration of the effects of surface area. This demonstration isn’t heavily focused on nanotechnology,but can be a spectacular finale that you add on to other nano demos like Intro to Nano or Surface Area. (It’s probably best as a substitution for Alka-Seltzer, rather than being performed with it.) It’s also just a crowd pleasing demo that briefly mentions nano.

Objectives

Big Idea:

Surface area on mentos makes soda explode.

Learning goals:

As a result of participating in this program, visitors will be able to: Describe how surface area makes soda explode.

Mentos Lesson Plan [13]

Pop Rocks - carbonated candy [14]

Submitted by Anders Liljeholm [4] on Fri, 09/23/2011 - 12:52.

I just learned that Pop Rocks are themselves carbonated. The fizzing that happens when you ingest them is because the bubbles of gas inside them are pressurized.

An interesting additional demonstration you could do - addressing the myth of pop rocks and soda. If you substitute Pop Rocks for Mentos, the soda spray is very unimpressive - 1 foot high at best. Pop Rocks do contain carbonation, but don't have the surface area needed for the Mentos effect.
