Talk Box in the Cave at Vortex Springs

Posted by Picasa
Just up from the gate there is a talk box. Its a five sided box that holds air. You can stick your head inside and have a conversation. Be sure to add a few puffs of 'fresh' air from your regulator to keep from CO2 from building up inside the box.

Its a good place to look for effects of nitrogen narcosis.

Yeah, co2 is 50% heavier than whole air, so new air at pressure blows stale co2 out of the bottom
