How Fast Is Ice Hockey Slap Shot?

Ice hockey slap shots hit 175 km/h. The 170 g rubber puck arrives at the goaltender in less than 0.4 seconds — faster than human reaction time. Goalies wear armoured masks; the alternative would be brain damage.

Bobby Hull's 1965 slap shot was clocked at 190 km/h — long before modern composite sticks. He famously broke a goalkeeper's jaw through the mask in 1968.

• Goalies wear armoured masks for a reason
