I tried a similar "experiment" once with Mother's California Gold. Only I used the torch directly on the wax in the can. (The wax had started to crack & crumble from not being used for a while, so, I figured what the hell, it's wax, I'll just melt it back together again.) WRONG!!! All was working well for a few minutes untill a small flame started & continued to grow to about a foot high. It would not go out. I started to panic & blew on the flame, spilling the now molten wax all over the top of my work bench. I now had a giant can of carnauba sterno burning like hell in the can & more burning on my wood topped work bench, I was able to put out the flames on the bench, but the wax kept burning stronger in the can. Finally lout of desperation I grabbed a big pair of channel lock pliers & grabbed the can & threw it out on the driveway where it finally went out. I now have a big mellted wax splash on my blacktopped driveway that looks like a giant bird took a huge dump! What was I thinkin".....P.S. I'll bet I'm the only one here that ever waxed his driveway.
