Invisible ink/Glow-in-the-dark pen
You may have guessed, but scout elves are very apt joke tellers. They’ll share one of their jolly gags with you—but you’ll have to work find the punch-line! First, elves write a riddle or joke on a piece of paper using a pen.
To solve the riddle, children can take a black light and shine it on the paper, revealing the punch-line, which your elf has hidden on the same piece of paper with invisible ink!
If your elf can’t find your black light or bring one with them from the North Pole, they can also leave fun riddles and jokes on notes or cards throughout the house for early morning giggles and fun.
