While the pope himself may not be Steampunk, you might be amazed at what is: the coronation stove. For those who don't know, it's been a tradition for a very long time to signal the election of a new pope (or the lack of a new pope) via colored smoke. More specifically, once the cardinals have all voted for the new pope during the conclave, the ballots are burned in a special stove in the Sistine Chapel, and the smoke is visible in St. Peter's square.
Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

This animated video, produced by Jewish Pathways, demonstrates how to wash your hands in accordance with Jewish law before eating bread. Besides cleanliness and holiness, the instant reason the rabbis call for washing before bread is to keep alive the memory of the proper treatment of teruma (the first priestly tithe that may be eaten only by kohanim and their instant families, and that must be eaten only in the absence of any tum’ah – ritual defilement).
