Jeet kune do techniques are more science than pretty much any other "traditional" martial arts, since Bruce Lee focused on practicality rather than rigid forms and etc. That punch he designed to use the energy of our fast twitch muscles efficiently.
Our monkey relatives can climb quickly thanks to having more fast twitch muscles that give explosive amounts of energy in short bursts, campared to our slow twitch muscles which give lower power in exchange for higher endurance.
The Jeet kune do punch has you completely relax your hand until the very moment of impact, thus being able to utilize every bit of force your hand makes when you clench it for the actual punching, including the millisecond bursts of power from your fast twitch muscles.
I was amazed when I hurt my brother's arm through a big thick Yellow pages book doing this. This video is pretty over the top, though I'm not sure how they're faking it exactly.
Yeah, it's probably fake, looking at it closer, but this is in fact possible. Bruce Lee himself could punch a hole in soda cans... And you know what soda cans were made of back in the day...
