What’s it about?

Although the phenomenon of dropping candy and mints into soda to release the carbonation has been around for many years, the effect of dropping a Mento’s mint into diet soda results in an especially momentous eruption of soda out of a bottle. Have fun with the following science experiment:

Topics covered

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

In this science experiment, when the Mento’s candy is dropped into the carbonated soda, which is filled with carbon dioxide gas, the gelatine and gum from the dissolving candy create an energy that breaks the surface tension of the soda. Many tiny ‘pits’ then form around the surface of the mints which are conduits for carbon dioxide bubbles to form. When the Mento’s hit the soda, bubbles immediately begin to form on their surface. When the candy hits the bottom of the bottle, the gas is released and pushes all the soda from the bottle up in the air in an amazing eruption!
