Keep your fingers on your hand, where they belong!
Okay, I know this doesn’t have much to do about skylights, but what a crazy demonstration!
A man shoves his finger into a table saw with a blade rotating at 5000 rpm. The blade stops in 5000th of a second at over 1000 g’s of force. Unbelievable.
There are over 60,000 saw blade accidents a year resulting in over 3000 digits being removed, which is over 10 per day. This saw would save a major disfigurement, medical bills, etc.
