We went with some friends from our ward/Sam's program to the Corning Museum of Glass. It was way cooler than I was expecting. I did not know anything about glass and I learned so much! I didn't know the consistency of glass when it is melted. During the hot glass show, they said it has the consistency of cold honey. They were just pouring the glass! It was incredible. Also, glass is used for so many things that I did not realize (optical fiber, microchips, etc.).
This guy was showing tension points in glass and if you hit the weak places (even softly) then the glass will shatter.
Rotating the rod so the glass wouldn't drip off.
Sticking the glass into a mold.
Spinning the glass so it will flare out.
The glass looked room temperature but then he threw a paper towel in it and it caught on fire.
