The green one on youtube is a small one, they have like 80-50% chance of surviving with broken bones which is 60-50 meters max. I don't want them to suffer, I want it to be fast and painless, I'm not heartless
. The dry Sinkhole though is 250m deep, 90 Million cubic meter in volume (world's 3rd largest after 2 in China), so you can have all xbox fans there and yet you have enough room for Stadia
.
The other photo posted is 211m deep, some call it "the well of the birds" as sometimes you find many birds flying in circles inside with lots of echos! There is a 4th one that hasn't been studied enough, as I'm aware, and might slide them right into the sea. We should throw just one there to know from the impact sound how deep it is.
