That would be Lexan made by GE and like products. 30 years ago, I designed the Bomar boat hatches (that you see on expensive yachts and Cigarette racing boats), used 1/4” Lexan in them for skylights, and I even tested their bulletproof claim with a 45 Cal. and a 30-06. It dimpled but stopped them cold. It will not however stop armor piercing rounds.
Great stuff. (but expensive)

Dr. Bill is also a college professor, Berkley and Chico, he is our are and has young children under 10 and grown kids almost your age.
I have listened to him on and off, he loves solving problems, any problem, from dropping food to war torn counties, a package at a time, instead of the pallets that brought out the terrorists to kill and collect them.
He was very interesting during the New Orleans disaster, for he shared with us some of what he was working on, as a problem solving scientist.
He solved the problem of dropping water to the trapped people, in his bathroom.
As I understand it, from bits and pieces, if the bottle is filled to a certain point with water, then sealed, it can be dropped into the flood zone and will float.
From odds and ends heard, Coca Cola stopped the plants and bottled water for dropping and got it out.
A year or so later, I heard on the news that FEMA was destroying thousands of leftover bottles, and I doubt that the news folks were smart enough to understand that they were not off the store shelf bottles.
Dr. Bill says that the people that stayed in the stadium, could have walked out, a mere 5 miles and the deepest water would have been ankle drip.
There is more, but I am distracted by the scanner, which is calling for a “Broken Arrow Training Exercise.......”, guess it is tonight and now....in Las Vegas.
