“Interesting Confusions”
1. Can u cry under water?
I would think no, because your tearducts will be closed secondary to water pressure, and hence, unable to bring up tears.
2. Do fish ever get thirsty?
All living things need water to survive, whether they drink it, absorb it by diffusion or otherwise obtain it, they must have it. Most of a cell's matter is made up of water so without water cells can't reproduce, and if a cell were to lose water it could and most likely would die, depending on how much water it had lost. And as organisms are made up of cells, the same holds for them, including fish. In addition, other functions carried out by organisms require water.
Seawater has a higher salt concentration than the body fluids of fish. Therefore, fish in saltwater constantly lose to the sea. These fish have to drink continually, urinate very little, and push the salt out through their gills.
Freshwater has a lower salt concentration than the body fluids of fish. Fish living in freshwater never drink. Freshwater tends to flow into their bodies.

Glue is made up of a substance that sticks to things and a solvent that keeps it liquid until you want it to stick. When you put glue on a piece of paper, the solvent gradually evaporates until the glue becomes sticky. When the glue is in a bottle, there is a space inside the bottle above the liquid that is full of air. So why doesn't the glue dry out? Well there's a limit to the amount of solvent that can evaporate to fill the space in the bottle. Once the space is full of solvent gas, no more solvent evaporates from the glue and the glue stays runny
