The property being demonstrated is refraction, where light changes speed and direction as it travels from air to water due to the difference in the medium's refractive indices. This causes the pencil to appear bent or broken when viewed through the glass of water.
The property being demonstrated is surface tension. Water has a high surface tension due to the cohesive forces between its molecules, causing the needle, which is less dense than water, to float on the surface instead of sinking.
Acrylic paint sticks to glass the best because it is durable, adheres well, and can be easily applied and removed.
change any property of the glass?
Blowing glass is a physical phenomenon, or 'property'.

Yes, scratching glass is a physical property because it is a change that can be observed without altering the chemical composition of the glass. It is a physical change that affects the appearance and surface structure of the glass.
A physical property of glass is its transparency, allowing light to pass through without scattering.
A physical property, such as hardness, is what allows a material to scratch glass. Materials with a hardness greater than glass (5.5 on the Mohs scale) can scratch it. Chemical properties do not directly influence the scratching of glass.
It sticks easier to glass. Or to flatter surfaces. Cloth or foam wont work. It sticks easier to glass. Or to flatter surfaces. Cloth or foam wont work.
