Take 2: Coke/Mentos Blast Off Geyser Fountain

This is such a fun and cool weekend project. Imagine creating a big fountain from coke? That is what we all did this weekend!

What you need: 7 Mentos , 2 liter bottle of Diet Coke. Diet coke works the best and optional Geyser Tube.

 




We got our geyser tube from Amazon.com . Very soon kids4fun.com will be selling this in the online store. But you can also make it yourself at home by rolling a paper to fit the mouth of the bottle. Make sure to position it such that all the Mentos drop at the same time. Think before you do it! Also make sure they are lined up and not be blocking

Mommy will be posting the video soon once she turns on her laptop.


Mommy Notes: How does this work?
When you drop the Mentos into the soda, the gelatin and gum arabic from the dissolving candy break the surface tension. This disrupts the water mesh, so that it takes less work to expand and form new bubbles. 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.  Source: Steven Spangler
