Whump.
************************************************* ************************************************** *****************************

When I was a stupid teen a friend of mine and I had the brilliant idea
of filling a 30 gallon trash bag we had placed in an empty 55 gallon
drum with Oxy/AC .
We put enough Oxy/AC in the bag to stretch it to the max and then tied
our cannon fuse inside the neck with enough duct tape to give an almost
air tight seal. We then put several bricks and a cement block on the
lid and lit the 30 second fuse. We were about 100 feet away behind a
tree when it went off. It was a darn good thing we hid behind that tree
cause bricks and concrete block pieces were flying everywhere. The 55
gallon steel drum did not split but it had a permanant bulge in the
middle of it. Similar experiments with gasoline and Oxygen yielded
results almost as spectacular . I'm just glad I'm not a kid growing up
now. What a difference 40 years can make. It is hard to believe that
this is the same country and a Cherry Bomb can get a kid thrown in
jail.

The buried 2-liter bottle just goes "whump". The neighbors don't even
notice. However, it does seem to result in no new tunnels for a
while.

I have been meaning to try another method of dealing with gophers. You
could use a two liter bottle to do this. Cut the bottom off the
bottle, insert the top into the gopher hole, and put dry ice is the
bottle. The cool CO2 will flow into the hole and force the oxygen out.

At least that is the theory. I have not tried it. But a good many
years ago a friend, Bill Torode, and I were looking for caves in
Northern Alabama. We found a sink hole with a lot of leaves in the
small entrance. We started in, but our acetylene lights went out when
we were about ten feet into the sink. We found that our light would
not stay lit below some level and figured it was CO2 gas in there. We
moved on and looked elsewhere.

More likely is that the decaying vegetation has used up the available
oxygen.

Excess carbon dioxide in your blood stream tells your body that you
need to find a better place to breathe.

Too little oxygen allows you to go to sleep forever.

You and your friend are lucky that you moved on.
