To perform our experiment we need a latex glove, a plastic bottle and a water container.
We cut the bottle in 2 parts and then we fit the glove on the top of the bottle.
If we introduce the bottle in the container we can see that the glove is filled with air
The air trapped inside the bottle is pressed and the glove is filled when we introduce the bottle in the recipient.
This increasing of pressure depends on the amount of water that comes into the bottle.
