“We were sorting out my dad’s garage and found 3 pots with some colorful bars. There is some kind of spring squeezed to a ring inside each of them. They have no smell, don’t burn, but smoke heavily. What can that be?”
A: "It’s so nice to know something other people don’t. The photo shows a refill for a lava lamp. The spring on the bottom heats up from the lamp and paraffin floats in water."
