Air and water are considered fluids. They are capable of flowing under the influence of gravity. The general rule about this flow is that denser fluids (such as water) strive to move down (in the direction of gravity) past less-dense fluids such as air, which will tend to rise against gravity and flow up. It is this directionality that is preventing the water from entering the glass. The air can only be displaced from the water by moving up; however, in this case the flow is blocked by the glass. This is why doing this trick results in a force being applied against your hand; the air pushes against the glass, which in turn pushes against your hand.
Interestingly enough, this trick can actually work in reverse. Immerse a glass in water, then start lifting it out of the water upside-down, being careful not to let the rim of the glass leave the water. Now you'll see the reverse happen: water staying in the glass because the air cannot get through the glass to push the water within back down...and as a result you have a force being applied trying to push the glass back into the water.

a way is you can use Archemedes principle and fill a glass of water bigger than the cylinder to the top. then place the glass in a bowl. carefully place the cylinder in the glass and make sure you submerge the whole cylinder.take the bowl with the water in it and pour it into a measuring cup and see how much water it is. that will be the volume of the cylinder.

Why doesn't a paper towel get wet when you put the cup inside of the water?
Water cannot fill the glass because the glass is already ~lled with air. The "empty" glass is full of air. So, air takes up space. Air is a gas. It has no size or shape of its own but will fill every space it can.
If you have a 4 oz and a 9 oz glass how do you get 6 oz of water?
Fill the 9oz glass. Pour the 9 oz glass into the 4oz glass until the 4oz glass is full. You now have 5 oz in the 9oz glass. Empty the 4oz glass Pour pour the remaining water from the 9oz glass into the 4oz glass until it is full. You now have 1 oz in the 9oz glass. Empty the 4 oz glass. Pour the remaining 1oz in the 9oz glass into the 4 oz glass. Fill the 9oz glass. The 4oz glass with 1oz in it can now fit a total of 3 more oz. Pour the 9oz glass into the 4oz glass until it is full. You now have 6oz in the 9oz glass.

How can you use fully empty in sentence?
I would not use "fully empty" in a sentence because it is redundant and unnecessary. If something is "empty", it's empty. You do not need to say "fully empty" because empty cannot be anything but nothing. There is no further defining words needed.The glass was empty.I carried an empty pitcher.My gas gauge read E for empty.
