I think they waaaaaay underestimated the weight of the wrecking ball in that
article. 68kg as the article mentions would be roughly 150lbs and I would say
that figure needs another zero or more like 1500lbs

steel 500 lbs/cu. ft.

Weight= 7 000 lbs.

Though I don't know what the actual weight would be I do know 150lbs is
waaaaaay off and likely the figure above is a lot closer to what it would weigh
