I shot the skaters with a Phantom MIRO LC320S made by Vision Research: Most speeds were around 3271 fps, but I shot the full body shot at 1200 fps.

The stick rigidity data collected by Dr. Evans and I is not a formal reflection on the manufacturers because the sticks were previously used and we could not find an ASTM standard to setup our test. The possibility exists that I put the support positions too close together, which would make the values lower. The players however gave us the sticks because they were “so used they were now flimsy”. Our data reflected this. If I had it to do over again I would test a new stick vs an old stick. Kettering University has done some research on this subject and we tried to setup our test apparatus similar to theirs. They applied the force to the foot of the stick. We applied the force to the center.

I thought this was a great video of a product that has normalized the process by constraining the 1 inch deflection measurement.

    You didn't buy new sticks to test those as your control?!?!?

  2. ZZ MM says:

    “thanks for STICKing with me, guys”

  3. BRAAP 15 says:

    2:20 that kinda spooked me. I thought the puck was gonna hit me in the face

  4. Mooba2 says:

    😂😂😂 "What is Destin talking about? I'm here this late at night for this?" 4:22

  5. Romanellochw says:

    Phil Kessel's snap shot is harder than this. Watch that slow mo video and you'll be in real awe.

  6. valueape888 says:

    A regulation puck weighs 6oz. Currently, the record for hardest slapshot is 109mph (Frk). Al Iafrate hit 105.2 in 1993 with a wood stick (!)

  7. It’s not that they didn’t put the correct flex number on the stick. Players usually cut their sticks or add “plugs” to make them longer, both alter the flex of the stick that is listed. The listed flex is what it is at the production length.

  8. It's like a fishing rod, and I also like my rods "whippier". lol

  9. Karin Busby says:

    I'm a physics teacher and a hockey mom. This made my morning

  10. Trynna watch the game here!!! 0:02

  11. at least goaile face cage es are made of titaniam

  12. Me before watching the video… I am gunna predict its about newtons 1st law an object stays in motion unless an unbalanced force is applied

  13. Destin I would love it if you would go back in and do a deep dive into this series. I am so hungry for more info!!! Fantastic job as always brother.

  14. josh loleski says:

    The reason why the number were different for the flex because their are different points of flex on different sticks

  15. dabear says:

    The thumbnail looks like a the thumbnail to a video game

  16. Cameron says:

    4:10 that’s actually wrong, each stick has a different kick point, find that and the flex is right

  17. Btw different sticks have different points they bend at.

  18. His slapshot technic isnt the best but he still shoots really hard

  19. Tommy Grön says:

    Just figured it out, you look very much like Mats Sundin, legendary swedish hockeyplayer that played for Toronto in NHL…

  20. Jeffrey says:

    Ya know what hockey question I need answered? Why do all the best goalies have the same hair?
