Because Glycerol and glass have the same refractive index. ie light is bent (refracted) by the same amount when the light travels from air to either the glass or the glycerol. Therefore when combined together you will only see the exterior substance (in this case glycerol) not what is hidden inside it.
I believe there is a similar affect with diamonds in immersed in water ie. they disappear. This is also apparently a good way to check if a diamond is real.
Glycerin has essentially the same refractive index as glass, so any light passing through the two is bent equally. Since both are transparent it's not possible for your eye to distinguish the boundary by a change in the angle of refraction, and the glass seems to vanish.
Glycerin is a clear, colorless liquid with a high refractive index, which means it bends light strongly. When glycerin is in a glass bottle, light passes through the liquid and glass without being scattered, resulting in glycerin being virtually invisible.
The ends of the wires will stick to the glass and become embedded in it once the glass solidifies. This creates a strong bond between the wires and the glass.
No, it can be manipulated when at around 1500ºC, It becomes soft and glass blowers can manipulate it to become what ever shape they want it to be.
The temperature of the glass become also 10 0C.

Invisible glass cleaner can be purchased from many websites. Among them Walmart, Target, Amazon, Advance Auto Parts, Invisible Glass, and many local grocery stores.
cause you can see through it
People use plexi glass in water and walk on that and that plexi glass is invisible in water.
Refraction of light can best explain the apparent bending of a pencil when it is dipped in a glass of water. This is due to the change in speed of light as it passes from air into water, causing the light rays to bend.

submerge it in a liquid that has the same index of refraction eg. water.
Glycerin has essentially the same refractive index as glass, so any light passing through the two is bent equally. Since both are transparent it's not possible for your eye to distinguish the boundary by a change in the angle of refraction, and the glass seems to vanish.
Refraction can best explain the apparent bending of a pencil when it is dipped into a glass of water. Refraction is the bending of light waves as they pass from one medium to another with a different density, such as air to water, causing objects to appear shifted or bent.
If you want the smaller glass to appear invisible in the liquid it contains, the index of refraction of the liquid must be equal to or very close to the index of refraction of the glass. Matching these refractive indices results in minimizing the reflection and refraction of light at the glass-liquid interface, making the glass less visible to the observer.
The spreader which is dipped in the alcohol is flamed, the fire will burn off on the spreader. It is sterilized now and could be used in the experiment.
