Varmetgetter - The explosive method

I ran across this gem in my nightly websurfing. What a wonderful invention! Its used to clear out burrowing animals from your property (gophers) by pumping 95% pure oxygen and 5% propane in the hole and then igniting it.
!blink!
I gotta say it again: Gas the critters and then ignite it? Hot Damn! Thats sounds like a weekend activity worth doing! I think the pictures are on the website are even better. Sure, there is a whole page dedicated as to why the "Varmetgetter" is superior to other gas and ignite systems (wait, theres more than one system!?). Like I need to be sold!
I think I really like the videos as well. Watch a few of them. The ooh, ahhs, and "holy cow" are great!
