The items needed are gummy bears and cups of water. Two types of gummy bears are used. The bears are placed in the cups of water.

Gummy bears are a hygroscopic substance. Hygroscopic substances absorb water. The bears' gelatin ingredient helps prevent the bears from dissolving in the water.

The gummy bears are left to sit. 9 hours later the bears are taken out of the water. We find that the bears are much larger than the original bears.

How big can you get your bears? Feel free to post your results in the comments section or make your own video.
