Why do gummy worms grow in water?

Gummy worms grow in water due to a process called osmosis. When placed in water, the Gelatin and sugar in the gummy worms absorb water, causing them to swell and increase in size. This happens because the concentration of solutes inside the gummy worms is higher than in the surrounding water, prompting water to move into the gummies to balance the concentration. As a result, the gummy worms become larger and softer.
