Note on Icarus Puzzle
The version posted online is not what was available at the March 2015 Puzzled Pint event. A more complex version of the puzzle was used, which included a step to hold the sun area of the page to a flame. When heated, special ink revealed a rebus of the puzzle solution.
If you'd like to recreate this version, start with the original version of the puzzle. To make the invisible ink, mix 1 teaspoon of baking soda with 1 teaspoon of water. Then, using a toothpick, write "HOT WINGS" in the sun. Or, if you're feeling artistic, you can draw a rebus image (see below). Draw lightly so that the lines don't indent the paper.
