One of the kids I knew growing up put a firecracker under a tin can with a lid...and yep! it got him across the cheek...big time. Has a scar today.
That would have been in about '47 or '48.
He went on to get a PhD in physics from Rice and was an expert on lightening and was a consultant to NASA when clouds were in the area before a launch.
He's still called "Bubba" in our hometown.
Darn near had that happen to one of us, set a M80 in a jar floating down an irrigation ditch. Neglected to duck, it went off and a big chunk of glass embedded in a tree we were standing near, but not hiding behind.
That irrigation ditch was good for all sorts of mayhem. Like the raft we tried to build that of course did not float.
