How a Hockey Puck is Made

Corny joke at...wait, where's the corny joke?

I don't know that I can ever trust How It's Made again if they're not going to include their signature corny joke in the segment.

"Certain minerals" (at 0:38) is way too vague for me. I want to know which minerals.

That 'carbon black filler' (at 1:11) looks dangerously powdery. I hope the workers are wearing correct PPE.

I am consistently amazed at how much of the manufacturing process is done by hand.
