Lisa shows us how to clean up spilled candle wax using an iron and a paper towel, a trick from Japanese Urawaza.
The household ingenuity captured herein really caught fire in the post-war period, when Occupied Japan's poor economy made a virtue out of frugal and clever homebrew products. The name Urawaza comes from gamer slang, referring to the programmers' back-doors that let players gain points, levels and advantage by doing something unexpected, and it's the perfect appellation for the surprisingly satisfying knowledge that you can keep your cut flowers longer by dropping a copper penny in the water, carry a heavy box more readily if you stack it atop a lighter one, and so on.
