Do you know what are the different types of glasses? How does a convex/concave galss work? What happens when you put someone's hand in a bowl of water while that person is sleeping? What is the top russian fighter jet/ american fighter jet (F 22 Raptor is not included as it is the best one but not to date)
Which is better a Mig 1.44 or an SU 47 Does anyone know the song "Chin high chest puff you step right to it choice is there ain't no choice but to pursue it" and "I'm addicted to speed its' everything that I need its' everything I dont' want but its' become what I need" (both songs are from driver parallel lines. Can't find em'

There are many types of glasses. Most commercial ones come from silicon dioxide (SiO2). But you can get the glassy state from alcohols or other compounds.
Here are some lists of different glasses (although technically, some are crystalline)

Convex/concave glass refers to the curvature. Concave is indented from the flat (like a cave), Convex bends outward. The change in index of refraction from glass to air causes these to act like lenses.
Whether an image is bigger or smaller depends on whether you are talking about a lens or a mirror.

has some basics.
If you put a person's hand in a bowl of water while sleeping, it may cause them to wet their pants.
Fighter jets are out of my league, but the F-16 is decent.

I could only answer one question. The types of glasses are the concave and convex. When you look at a concave glass, the image becomes smaller. When you look at a convex glass, the image will get bigger. Try looking at a spoon...

Man, take a riddelin or something. That is about seven different questions all piled into one long sentence. Take a deep breath, count to ten, then start retyping one question at a time.
