Indoor sparklers

This is probably a terrible idea, but one can afford to be a little reckless in honor of New Year's Eve.

We all agree that sparklers are the best thing ever, no? Except it's kind of a bummer that you have to leave the party to set them on fire outdoors so as not to burn things down indoors. So, what if you had indoor sparklers? Would that not be rad? Something like a glorified incense stick (which sparklers pretty much already are) that you could light indoors without destroying furniture or your nice hardwood floors or setting drunk people on fire by accident. And maybe they would even smell nice...
