10MPH ideas that you'd love to see, but probably not anyone else

What are some 10 Minute Power Hour episodes that you personally would love to see, but will likely never happen, either due to safety concerns or lack of popular demand?

I personally would love to see the boys visit a gun range and pop off a couple rounds, gradually increasing in caliber for more boom boom. Move up from a .22LR to 9mm and eventually up to 12g shotgun shells. I picture Danny being VERY rattled by the loud noises and the reverb, and Arin getting surprisingly into shooting.

I also want them to try out one of those skydiving-on-land experiences where you stand in a giant fan chamber and get lifted up by the air flow. Would be SUPER fun, but I can't imagine any possible way to film it, except maybe with nausea-inducing GoPros.
