Does sugar affect bubble size in gum?

The more sugar there is in gum, the smaller the bubbles will be. This is because sugar molecules take up space in the gum, leaving less room for air pockets to form. As a result, the bubbles that do form will be smaller.

In addition, sugar can also make the gum more elastic, which means that it will stretch more easily and be less likely to pop. This can also lead to smaller bubbles, as the gum will not be able to hold as much air pressure before it bursts.

If you want to blow bigger bubbles, it is best to choose sugar-free gum or gum that has a low sugar content.
