Haha I still don't get it. What happens with the wax after it has less/no scent?
HA! Yeah, I sort of don't get it either but my mom's obsessed with them so *shrug*. I've actually kind of hated these things since childhood when a burner tipped over and spilled on my bare leg giving me quite the nasty burn I guess that was my lesson for climbing on the counters I have to admit, they do make the house smell really nice though but once the smell is gone...it's just wax. I guess you could recycle the wax again by adding more essential oils or extract and you could probably consolidate them and make a candle if you wanted.
