there can’t be any amount of ear protection that makes that safe.

Yeah, cool but WHY? Is that the only way to keep the alligators away?

No, seriously, why did they they blow something up in there?

I can’t believe they were still in the hole when the blast was triggered. Are they insane?

They were not.

They are now.

also, did they need be IN the tunnel when they did it…i mean, seems they could have run some extra wire and detonate that from just outside the tunnel.

It’s no fun if you’re not inside the cannon when it goes boom? :woman_shrugging:t3:

It occurs to me that the amount of explosive was quite small and that they were a safe distance away from it. Someone has suggested that they were clearing a side branch. But what if it is an expedient way of dissipating low levels of methane? My guess is that kind of stuff could build up slowly to a level that it becomes dangerous if it were to explode - so they nail it before it becomes an issue. It really wouldn’t take much explosive material to demonstrate that effect.
