How do you carry a "wisp of smoke"?

One of the spell components for the Gaseous Form spell is a "wisp of smoke".  Have you considered how your character is going to carry a wisp of smoke?  Or how your wizard will manage to use the wisp of smoke in the spell?  Fortunately for those of you trying to follow the rules of the game, this tidbit rule is irrelevant.  According to the description of spell components, you can ignore most components, and the complexity of obtaining, carrying, and using them.  But you cannot ignore the components that have a gold piece value attached to them, or an experience point cost.  These you should account for.  I do wish the authors of the material had kept to spell components  that would be reasonably portable, unlike the wisp of smoke.
