Put raisns in a bowl of water and let them soak for at least an hour
When you place a raisin in salt water, the water around the raisin becomes more concentrated with salt due to osmosis. This causes the water inside the raisin to move out towards the salt water, resulting in the raisin shrinking and becoming wrinkled as it loses water.
all you need is an empty water pistol and a bag of raisons
A raisin will float in soda water because the gas bubbles in the soda water attach to the rough surface of the raisin, making it buoyant.
When the dried raisin in placed in water it absorbs the water so making it plumper and less wrinkled.
If a raisin is placed in a low concentrated sugar solution, water will move from the high concentration inside the raisin to the low concentration solution, causing the raisin to swell up and become plump as it absorbs water through the process of osmosis.
It may vary upon how much time it has been kept in water. And also type of solution in which it is kept. Since the raisin has less water and water always moves from an area of more water to area of lees water, the raisin will swell.

If a raisin is kept in a salt solution, water will move out of the raisin due to osmosis. This will cause the raisin to shrink and dehydrate as water flows from an area of higher concentration (inside the raisin) to an area of lower concentration (the salt solution).
A raisin becomes turgid when placed in a hypotonic solution, causing water to enter the raisin through osmosis. This influx of water causes the raisin to swell and become firm or turgid.

Yes
A raisin is a dried up grape, if it is placed in water it will absorb water and regain some of its original shape and size. The process involved is called osmosis. It happens when areas of high concentration (the sugar solution inside the raisins) is separated from an area of low concentration (the water outside the grape). Physical forces try to balance the concentrations so the water passes through the grape skin (technically a semipermeable membrane) into the grape and plumps it up.
