This is well beyond what I could do in my decrepitude.

It's a Mythbusters episode, but unfortunately, that show has ended.

The last adventure of this sort I did was in 1985, just before I moved
to the Bay Area/   We poured 200 pounds of propane down a mine shaft
and dropped in a flare.

If I can pull this off, actual literal youth will flee, wanting nothing to do with what I have in mind.  Read on please.

Get one of the modern V-rated tires, good for 200 mph, rig it to the front of a really fast car, or even just a normal pickup with the carrier mounted to the front tow attachments.  That I could build.

We rig up a compressed air system that drives a cruciform manifold with four nozzles, kinda like a Nazi sign with nozzles at the ends of the four bent things and nozzles at the ends.  The compressed air is at the hub.  Get kiting across the dry lake bed, open the valve on the compressed gas, get the wheel spinning, brake the truck to release the wheel which accelerates and slams into a target.  We could see if a 200 mph motorcycle tire could punch thru a parked car.  Or, see how fast we could get the wheel going, never mind hitting a target.  See how fast it could go before the centrifugal force caused the tire to explode.
