70 / 100
Mostly True

Glass cracks faster than 3,000 mph, and a camera must shoot at 1,000,000th of a second to capture it.

Infact verdict: Mostly True (70/100).

The claim that glass cracks faster than 3,000 mph is supported by multiple sources, including TM Atlantic and Mountaineer Glass WV, which confirm the speed of glass cracking at up to 3,000 mph. The claim about the camera needing to shoot at 1/1,000,000th of a second to capture glass breaking is partially supported. While Diomedia supports this speed, Picturecorrect suggests a slower speed of 1/10,000th of a second is sufficient for dramatic effects. Therefore, the first claim is mostly true, while the second claim is mixed due to conflicting evidence.
