Chinese air...

Cut'n'screwed more siding up on the south side today.  Noticed something interesting when I started on the SE container.  I'm drilling pilot holes into the top edge of each container - into a piece of square tubing that was welded up and sealed when the containers where manufactured.  The first hole today and I heard air rush out once I punched through.  That container was manufactured in Shanghai China in April of 1999.  That was some old Chinese air I just let loose in Texas. 60,78,39,0,B

Be careful there. I saw a guy grinding on a backhoe gantry when it exploded. He was burned pretty good. The story is that if there was moisture when it was welded up it corrodes and produces hydrogen gas, he had ground through the rust and sparks went into the H gas. It was a BIG bang. I would drill a hole before I started any spark producing work on a closed section of pipe or tubing.

Everything else in Texas is from China now days. Now I guess we have some Chinese air to go with it.

Doesn't have to be a perfect seal to cause a rush of air. The original air inside leaked out long ago but in microscopic hole allow air in and out at a slow rate. Add a few degrees temperature difference and whatever air inside become excited and pressurizes. The military has been using this idea for years for storing ammunition long term. Air molecules can get past seals but water molecules can't. Used to have ammo cans popping and whistling when exposed to direct sunlight back in my day.

An interesting concept. I think the folks who drill core samples into Greenland's ice layer have found similar air pockets, only thousands of years old.
