The key is to eat shit 50 times beforehand attempting this until you eventually get it right and only post that final time. Its basically the same mechanics as doing a jump on a flat surface, just significantly harder.

This is such a high risk, eat major shit move too.

Catch a foot and rotate awkwardly into concrete while falling face first into concrete.

Miss board and fall into concrete on your shoulder.

Hit board but slip out and crack against metal stairs.

I'm always amazed by people that pull off crazy gaps while skateboarding.

Not a single piece of safety equipment either. Too cool to wear a helmet, let alone knee/elbow pads.

I split a helmet in half once while snowboarding. Went off a jump, landed fine, then caught my heel edge with a ton of speed and it whipped me onto my back and head.

I got up a bit dazed and my friend comes over to check on me and is like holy shit your helmet is cracked in half. The only thing hold it together was the plastic outer cover.

That helmet saved me from major injury or death that day. I can't understand why anyone nowadays rides anything without at least a helmet.

Yep, I'd been told that years before the first time I was fitted for one.

I was riding my bike to work one day and slid on some wet leaves. The bike went completely sideways. My head wanged the pavement hard enough to crack my helmet.

It would've been so much worse if I had not worn my helmet.

That is lance mountain. He has been skating 47 years and IS wearing kneepads, the most important piece of gear to fall safely in a pool.

Don't care how cool and great you are, wear a helmet. If not for your own safety, then to be a good role-model for kids who look up to you.

Nah he's fucking right. That's why Tony Hawk insisted on wearing protective gear

He’s wearing knee pads

Good call, hard to see them in this 144p gif. Still nothing protecting the most important body part.

Lmao, gonna call hard to see on the knee pads but expect to see his buttplug at that same resolution

It's entirely different from jumping on a flat surface. If you were to actually jump off the board you would just fly away from the wall.

If this is real, he basically just raised his legs closer to his body and lowered them at exactly the right time

candidateforhumanity t1_ir1ivf5 wrote

for every action, en equal and opposite reaction. for him to raise his feet without exerting pressure on the board he would have to be 1. not standing on the board while going up and 2. have his head lower to compensate.

he is jumping on his way up and the curvature of the wall catches up with his trajectory, that's all. you won't magically keep flying away from the wall in a curved path

TheoreticalJacob t1_ir1i7dt wrote

No it's even worse/better. He has to actually jump a tiny bit since his legs hold the force of him continuing into the wall. So he needs to jump a tiny bit, but not enough to completely overcome his momentum because he can't get it back.

This trick boggles my mind, I think the video has be to be rotated or something.

Edit: I think I can see it a bit better, just really impressive

gopherdagold t1_ir40n17 wrote

You can see his lower body counteract the jump at the same time so the force of the tiny jump is still applied but the average momentum of his body doesn't change. Essentially the board/his feet see a jump, his torso sees a dip, and his center of mass sees no change

I love it. "It's just like doing something dead simple, except is incredibly hard."

Danny-Dynamita t1_ir38121 wrote

He retracts his legs at the perfect time while conserving his momentum and puts them back in place very neatly.

No jump done at all, it’s not gravity but rather himself who drives his legs “down”. It also shows a level of precision worthy of a fucking atomic clock.

Hamburgr t1_ir35cbd wrote

Late to this is post, but look carefully at his legs. He's not "jumping", he merely retracting his legs toward his body and it gives the illusion of jumping. As someone else pointed out, momentum does the rest.

ignaloidas t1_ir3w9ot wrote

It is jumping. Merely retracting your legs would send you straight into the wall. Defining newtonian principles in a centrifugal system is somewhat unintuitive, but you do need to exert force upon the skateboard to go around the rails.

Hamburgr t1_ir3xfvq wrote

He would go straight into the wall if he continued in his path for a significant part of the curve. This is obviously an approximation, but he's only in free motion for like 3-5 degrees of a circular arc. That's not a lot in the grand scheme of things. After which, his feet are back on the board and he receives the necessary centrifugal force again to get back in the path of the arc.

Edit: Keep in mind that he keeps his current velocity vector when his feet leave the board. The absence of his feet on the board doesn't mean he suddenly gets sucked into the wall (where would that force come from?)

ignaloidas t1_ir4c02x wrote

Inertia is carrying him into the wall, as there is no force that's holding him away from it. Without any velocity into the wall he wouldn't be able to ride it.

Hamburgr t1_ir4vieh wrote

We agree that motion would be similar to releasing a ball that you are spinning in a circle by rope. When released, it continues with the instantaneous tangential velocity at that moment. However, the skateboarder's center of mass (lower torso) is somewhere on the order of 2.5 to 3 feet away from the ramp surface. Fundamentally his circular path of motion is offset from the ramp surface. Over course of his free motion from release to re-contact, he's only in the air long enough for his center of mass to get closer to the wall by like 3ish inches. Therefore, he can clear the ladder and quickly get back to the board before hitting the ramp wall.

You’ve never tried a hippy Jump on a skate board. try exerting force onto the thing which requires constant momentum moving forward. If you exert down and backwards force it’s already over. And the board is gone.

mattswingen t1_ir4kpxp wrote

You carry an insane amount more force than that board so you have to detach, not jump.

[deleted] t1_ir2n7tw wrote

It's a hippy jump so you find some hippies and use them for practice.
