I had always thought that water didnt have its own shape, that it takes the shape of the object that its placed in. in the picture i have attached it shows water having a sphericle shape, as if it has a skin on the outside keeping its shape. i thought water was very maluable and that its molecules are freely floating (yeah i know that sounds like the scientific explination of primary school, but thats the only way i know how to explain it, but its the general idea).. i think.

My daughter dived underwater in the swimming pool and screamed as loud as she could. I was right next to her with my head out of the water, but I could only detect the tiniest sound, at the end of the scream. But when I was underwater with her, I could hear most of the scream. Why?

If I half fill a jar with hot water and close it and leave it for a short time, not much happens when I open the jar.  But if I close the jar and shake it vigorously, when I open the jar there is a lot of pressure built up in there.  Why does shaking the jar do this?

Does the honey and the sugars react with the water in the bread?

I've notice for some time now that when I leave bread inside a plastic bag above the fridge, after a day of two, the water or humidity inside the bag or the bread starts to acumulate below the bread, to a point that you can actualy see water droplets, while other parts of the bread are completely dry and hard. Note that the bread is OUTSIDE the fridge, not inside, and most of the times the bags were tightly closed.

This certanly doesn't happen if I leave the bread anywhere else, so it must be an effect of the fridge. Could it be some kind of magnetic effect that makes the water molecules try to "stick" to the fridge, and thus they acumulate bellow the bread (where is closest to the fridge)? Or does it have something to do with the vibrations of the fridge?

Also, I leave a box with medicines above the fridge? Is it safe? Or the same effect could adversely affect them?

Cheers!

If you had stood outside looking up with your mouth open in the UK's worst snowstorm in the past 10 years, how long would it taken for the snow to fill your mouth with 200ml of water?

Would it have been more energy efficient to keep yourself warm all that time or to transport that 200ml of water to a tap in the area that the snowstorm happened?
