I would be real careful with snodog's idea. Having experimented with homemade Napalm in middleschool, I can tell you that a little accelerant and burning plastic is a bad idea (especially on unprotected nuckles, it's amazing how anybody survives childhood). If the cotton balls and petroleum jelly are already in the straw, be prepared to put it out REAL quick, and wear gloves and good protective clothing. Don't do it around anything else that is real flamable. It other words, if you use that method, try not to get a Darwin Award, be careful.
