Here's a cool domino spiral of candy corn that seems impossible to pull off. How can these lightweight triangular pieces of candy perfectly knock each other down without leaving one kernel standing? Explained by YouTuber FlippyCat: "After trying a few techniques, I ended up free standing the candy corn on top of mini black dominoes, which blend into the black floor. The entire 221 pieces of candy corn fell without stopping!" Aha! So it's a trick, and a pretty sweet one at that.
