What does Osmosis mean?
Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane. The important thing to remember is that osmosis is the movement of WATER ( or other solvent ) not the particles dissolved in the water.

Where i got the info from

Why did the water gummy bear get bigger?

the water gummy got bigger because if you think of a net around the gummy bear the water can get into the net because its small but the sugar and the salt cant because its bigger and the water can get into the net!
