About 20 years ago an escape artist did a live national tv event here. Trick was to escape from a buried glass coffin. A buried in cement glass coffin. In the trial run they used sand. They did not account for the extra weight of the water. The coffin collapsed and they could not dig him out quick enough. It was all live with no delay. Very sad.
I can’t imagine anyone NOT watching this! Terrifying though it is....
