This very clever gizmo solves a problem that humans have struggled with for hundreds of years: the stupid mess of dripping wax that happens every time you light a candle. (OK, to be fair we struggled with this a lot more hundreds of years ago than we do today, but still.) But now you can capture that wax and turn it into another candle, creating an infinite candle!

Well, not quite infinite, says FastCoExist:

Each time the Rekindle Candle burns, there’s a little less wax left, and eventually you’d have to start over with a new candle. How long it lasts, Shine says, depends on the specific candle — some burn faster, some are drippier — but you might be able to reuse the wax as many as five times.

If you’re anything like us, you always think how nice it would be to light a bunch of candles but you never actually do it. So we’re thinking this candle could last you the rest of your life. Unless, of course, the power grid goes down permanently, and we all have to use candles for functional light, not just atmospheric decoration. In which case, you’re going to need more than one candle — but a lot fewer than you would have needed otherwise.
