Why does cold water sound different from hot water when poured into a hot water bottle? I recently had a senior moment when doing my mum's hot water bottle. When pouring the water into the bottle I was alerted to the fact that something was wrong because it didn't sound right; I touched the kettle and, sure enough, I hadn't put it to boil and it was stone cold. Why the different sound?

How did this spiral of ice form?

This ice spiral is roughly 1 1/2" tall, found in a frozen pool of water about 2" - 3" deep on a boulder on Tryfan in Snowdonia, Wales at about 2500' on a day when the freezing level was about 500'. There were no overhanging boulders/cliffs etc. How did it form? In other pools, and in the background in this pool, there were 'ice mushrooms', but nothing like this strange spiral formation. What explains the bubbles on the inside? What explains the spiral shape?

Microwave vacuum trouble

When I reheat last nights curry in a microwave and cover it in clingfilm, the moment I take it out, the clingfilm tightly covers all the crevices and projections of the curry's surface. It is as if there is a vacuum inside. How can this be? Surly nothing has left the covered bowl.

P.S. while the curry in in the microwave the water evapourates and causes the clingfilm to bulge, but when I take it out and the water condenses, there is less pressure inside than before I heated it.

What sort of vibration would be able to hold a mass amount of water Okay, so I have been studying structure, and, correct me if I am wrong, does the universe give a perpetual sound or vibration? if so, could that sound be used to hold molecules together, i.e. water?

evolution: animal intelligence, land vs water Could an animal as intelligent and advanced as humans have evolved over time if nothing had ever evolved to live on land? Or, could it be possible for any current aquatic animal to evolve over time to a stage where it was as intelligent and advanced as humans?

Why are all plants not clear? I put some flowers in a vase with red food colouring and the petals turned red. Why do petals not take on the colour of normal water, clear?

How much electrical energy could be produced from a water turbine installed in the mains pipe to a house? Every time a tap is turned on in a house, water flows at mains pressure. If a turbine were installed in the pipe that supplies a house, how much electrical energy could be harvested? The electric supply would be intermittant, but might be enough to power a smart water meter for example.
