An egg placed in a glass half-filled with water will sink to the bottom if it is fresh, as the density of the egg is higher than that of water. However, if the egg is not fresh and has started to go bad, it may float due to the accumulation of gases inside the shell.
One way to turn a glass full of water upside down without spilling it is to place a piece of cardboard or a small plate over the mouth of the glass, then flip the glass upside down while holding the plate/cardboard in place. Once the glass is upside down, carefully remove the plate/cardboard to reveal the water remaining in the glass.
You will observe a pencil on a glass of water. Unless you're not looking that way, in which case, you will observe whatever you happen to be looking at. Unless, you're blind, in which case you won't observe anything.
The air gets trapped, and if the glass is brought deep enough under the water the air will be pressurised and will take up less space.
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
If the glass has a hole in the bottom and you submerge it upside down in water, the water would enter the glass through the hole until the air pressure inside and outside the glass equalize. Once this happens, the water would stay at a level inside the glass equal to the height of the water outside the glass.
When you place a lime on a glass of water, the lime releases its juice into the water, adding flavor and a hint of citrus to the drink.
When you put a drop of food coloring into a glass of water, the water will turn that color.
You place the water glass on the right of the plate in the "corner" of the place setting.
This is due to condensation. When air comes in contact with the glass it condenses(this happens only when the water inside is cold).
