When your put smarties candy in soda does it fizz?

Here's why:

* Smarties have a sugar coating: This coating dissolves in the soda, releasing sugar into the liquid.

* Sugar is a source of carbon dioxide: When sugar dissolves in soda, it reacts with the carbonic acid already present in the soda. This reaction releases carbon dioxide gas, which causes the fizz.

The more Smarties you add, the more fizz you'll get!

Just be careful not to add too many, as it can make the soda overflow.
