Harry Potter Wands That Shoot Actual Fireballs: Incendio!

Because housefires aren’t going to just start themselves, manufacturer Wejioin is selling these Harry Potter inspired (but by no means officially licensed) wands on Amazon (affiliate link) that actually shoot fireballs. To operate one, you just pack a small piece of flash paper in the business end of the wand, then push the button at its base to heat the coil inside, igniting the flash paper and causing it to shoot from the end like a fireball.
