I was at Lowe's tonight (just like Home Depot for those of you who don't have one) making a last minute frantic purchase during tech. As I walked past the tool department my neck snapped to attention as my feet came to a screeching halt. What are those little bottles my brain screamed... they say C02!! All thoughts of the tech that desperately needed my presence faded, as I was drawn toward the display. A belt clipped, C02 powered, portable pneumatic tool kit. Hmm... tiny portable fog machine? So here's the deal. The stuff is sold by Kobalt... which I think is Lowe's house brand. But it's apparently made by blue rhino the propane tank exchange people. They have a regulator kit for $100 that screws onto these cute little C02 bottles. The regulator input looks sort of like what sits on my barbecue at home... but it was kind of hard to tell in the package. The output is just a standard quick release for hooking up to your pneumatic tools... which could easily be fitted with a standard blow gun nozzle. They have these nicely sized little 9oz and 20oz bottles, that apparently you exchange for a full one just like the propane tanks. It's an area that would need a little SAFE experimentation, but it seems like there are a lot of potential special effects uses for this little guy.
