Why does bubble gum make larger bubbles that chewing gum?

Chewing Gum has a higher gum base content which makes it more elastic. This elasticity makes it more difficult to stretch the gum far enough to create a large bubble.

Bubble gum has a lower gum base content and more sugar. This makes it less elastic, but also more flexible. It can be stretched thinner without breaking, allowing for larger bubbles.

So Why?

Ultimately, the difference between bubble gum and chewing gum comes down to the ratio of gum base to sugar. Chewing gum has more gum per gum, while bubble gum has more sugar per gum.

If you want to blow big, long-lasting bubbles, reach for bubble gum. But if you're looking for a teeth cleaner, stick to chewing gum.
