I.C. Fermi 1st G Why is the aluminum case not deformed if merged in the water? The pressure of the water on the container acts in all directions and from bellow too!

Ice is less dense than water but it's behaviour is not common. Most substances become more dense as solid.

I.C. Fermi 1st G. Have you never put a bottle of olive oil in the fridge? Why it forms a deposit on the bottom? It's solid oil and it doesn't float as ice do. Michelle is explaining about.

Hello! My name is Francesco Morri and I am 11 years old. Today I show you how to make a Cartesio's little devil at home. For this experiment we need: a transparent plastic bottle (with its cap) almost completely full of water; a syringe without the needle; some iron wire; 3 iron hex nuts; 1 small weight to be put into the syringe (in case the 3 iron hex nuts are not heavy enough).

Now that we know better about gases and heat we can understand how it works the climate!
