Considering I've just polished off half a jar of jam, you could say I'm a fan of all things preserved. But inedible LED jams? JellyLamps' bright hues make me sad I can't slather a knife-full on a bit of crust.
When turned upside down, the LED light inside each jar of JellyLamps jam switches on, and glows neon. When flipped over, rightside-up, it looks just like a normal jar of jam - albeit, one that's made from fruit plucked from the bushes of Chernobyl.
