you can soak it in a high concentration of salt water which causes it to lose its turgor pressure ,therefore it shrinks in size by diffusional water from inside the potato moves to the salt solution)
The force that causes turgor pressure is osmosis.
When the turgor pressure is low in a plant it will start to slouch and wilt.
hydrostatic pressure or turgor (same thing)
Turgor pressure is usually calculated as the difference between water potential and osmotic potential. In herbaceous plants turgor pressure is almost solely responsible for maintaining an erect habit. Wilting of leaves is due to loss of turgor in the leaf.
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
Turgor Pressure
The amount of water in the cells of a vegetable affect the turgor pressure in the cells. The turgor pressure is how much pressure is in the cells. If the cells of the vegetable do not have enough water, the turgor pressure is low, so the plant wilts, making the vegetable look shriveled or small. If the cells of the vegetable have the right amount of water, the turgor pressure is high enough to keep the plant from wilting, so the vegetable looks healthy. If the cells of the vegetable have too much water, the turgor pressure is very high, and the cells may burst open, making the vegetable look shriveled and small.
The force that causes turgor pressure is osmosis.
A plant wilts when it has a decreased turgor pressure.
Osmotic pressure across the cell wall, here called Turgor Pressure.
When the turgor pressure is low in a plant it will start to slouch and wilt.
