Why do my fingers get pruney when wet?
Fingers may wrinkle when wet to help people grip wet objects, find researchers, who say the pruney feature may have helped human ancestors do the same in wet conditions. When a person's hands and feet are soaked in water, wrinkles eventually develop on the tips of fingers and toes.
For a long time, people thought the water caused skin to swell up and get puffy. Now researchers believe wrinkly fingers could be an autonomic nervous system reaction. Because it's easier to pick up wet objects with wrinkly fingers. Wrinkles on your fingers may give you more grip, kind of like treads on a car tire.
- The cause of aquagenic wrinkling of the palms is unknown but relates to sweating. It may be caused by a salt imbalance in the skin cells, which results in increased water retention within these cells and increased transepidermal water loss.
- Remember, when making jams without refined sugar, it will not gel the same. Don't expect a hard-set jam. Rather, be excited about an all-natural fruit flavored spread that can do double time as a topping for ice cream or French toast, or a side dish! If you want your jam to gel, add no-sugar needed pectin.
- Coarse-grain white granulated sugar is best for jam-making as it ensures a good clear jam, but fine caster sugar can also be used. The coarse grains dissolve more slowly and evenly, giving a better result. Granulated sugar with added pectin is also available, but it shouldn't be necessary to use this.
