Exploding Glass Filmed in 343,000 FPS Slow Motion

The Slow Mo GuysDan Gruchy and Gavin Free filmed exploding glass in 343,000 fps slow motion, making it the slowest they have ever recorded. To compare the incredible speed of the glass cracking from the thermal shock of being heated and then suddenly cooled, Free filmed Gruchy’s reaction time to having water poured into his eye, and played them back side-by-side.
