For those times you forget your Mobile Qurbana Kit...

Here are the plans for a Soda-Can Alcohol Burner

My idea:

Roughly the same thing but with a couple strings (or if you're lucky pieces of chain...or perhaps four long strings of paper clips), and a couple chunks of incense (if not available, some sweet smelling dried up flowers??), and BAM...Hobo-Censor

For those times you just need it...
