Growin' up on the Allegheny River hills, one of our favorite outings was to take Dad's hatchet, head out to the river hill, find a likely looking wild grape vine growing high up into the trees on the hill, cut it off, and swing out over the hill. At times, you could be 40 feet in the air, as the hills are quite steep. And sometimes, just when you were out there in space, the whole vine would come down outta' the tree, and you'd roll another 50 feet after you hit the ground. But we'd just get up, find another vine and do it again.
Another favorite was the carbide cannon. As a kid, many miners still had their carbide lamps that attached to their hardhats, and you could buy a pound of calcium carbide at the Freeport Hardware for a quarter. You take a one quart empty paint can, and with a nail, smack a single nail hole through the middle of the bottom of the can, put in 15 or 20 "rocks" of carbide and a little bit of water, seal the lid on the can and hold a finger over the nail hole as the pressure built up. (Acetylene gas). Hold the can out with two hands at arms length, and your buddy strikes a match under the nail hole. The explosion launches the can lid into the air, and it sails back down kinda like a UFO. Well, if a 1 quart can was good, a 1 gallon can must be much better. 1/4 pound of carbide, a pretty good shot of water, and plug that nail hole. I told my pal to hurry up and light it; the can was gettin' hot. The recoil from the explosion blew the can outta my hands into the dirt, never did find the lid, and the fireball blew off my eyebrows and lashes and some of the hair on the front of my head, along with all the hair off my arms. Ah, the good ol' days.
