Many of the properties of Prince Rupert’s drop are due to unique properties of glass that are not shared by lead or tungsten. Rather, the lead would yield and release the stored compressive forces due to the shape and cooling that occur in this glass. Lead will still be lead and tungsten will still be tungsten. Glass is significantly stronger than steel or titanium. The theoretical limit for glass 2.6 million psi! But in common situations the normal tensile strength is set at 10,000 psi. Much much less. This is because glass is brittle. The smoother the surface the more stress it can take.

Heck, I wouldn’t touch that will someone else’s @#$%.

I wouldn't touch it with Billy Jeff's @#$%, and I don't think he would either.

FRAMES PER SECOND

When you hang on gun forums as much as I do, 'fps' can only mean 'feet per second'. Thanks ;-)
