First of all, range safety rules are foremost at my private range. I have been shooting competitively since I was 12 years old. I got more advanced marksmanship and sniper training in the Army during the Viet Nam era.
Tannerite is frequently used on my range purely for entertainment. Who doesn't love things that go boom!
When I find a steel storage tank of the proper size, (100gal +/-) I cut it in half. 5-10 pounds of tannerite ( I make my own) will send the tank 100-400ft in the air.
My neighbor Karel entertains us regularly with his risk taking antics. On this occasion he flew his powered parasail while wearing his GoPro for an aerial perspective.
Last weekend Karel drove his Polaris Ranger through a huge brush fire, but that's another story. Moonshine was involved.

Karel and I carefully planned this ahead of time. We coordinated the explosion to go off when he was in the right position. From his perspective you can see that he was not in any danger but the spectators from the ground view didn't know that. I expected it to go that high as we have done this many times with different loads and different tank sizes. The height in this tank was 380+/- feet.
