  Don't tell Elon.  He will do something stupid like useing a boring machine on the kid while calling everyone else a pedo.
context: Hundreds of rescuers in Vietnam battled Monday to free a 10-year-old boy who fell into a 35-metre-deep hole at a construction site two days ago.
  The boy, named Thai Ly Hao Nam, fell into the shaft of a hollow concrete pillar just 25 centimetres wide, sunk as part of a new bridge in southern Dong Thap province, apparently while looking for scrap metal, a rescuer told AFP by phone.
  "We are trying our best. We cannot tell the boy's condition yet," the rescuer said, identifying himself only as Sau.
  According to media reports, rescuers have tried drilling and softening the surrounding soil to try to pull the pillar up to save Nam.
  Authorities "are not sure about the current condition of the boy. He has stopped interacting with the outside though oxygen had always been pumped into the" hole, the Vietnamese Tuoi Tre newspaper reported. >
  
  Bad news. Even if they pump oxygen into the hole, Carbon dioxide's weight is 44u while oxygen weight is 32u. Meaning co2 is heavier than oxygen and will fill the hole quite fast while the pumped oxygen floats above a layer of co2. The child might already be unconscious ...
  Accidents happen, but it is infuriating that the hole was not properly secured. >
  
  Absolute nightmare fuel. 
  Poor kid, can’t even imagine how horrifying that would be. I really hope he’s alive but would be shocked if he was… >
  
  My worst nightmare...I still get all antsy thinking about the cave diver who got stuck head first with his arms jammed against his chest in the Nutty Putty Cave system in Utah. They almost had him out when the pulley they were using broke and he went even farther in. Poor bastage is still there...
  That, kids, is why you don't go into the part of a cave called the Birth Canal, or even go into a cave at all... >
  
  That one is my worst nightmare. There’s another where a guy evading police climbed down into a false pillar in a supermarket and got stuck. Maybe don’t read up that one…
