    On one side of the pointy ends, it looks kind of ripped, and you blow in there.
  • Question
    How do I fold the two side creases in to make pyramid?
    Community Answer
    Community Answer
    Hold the piece of paper as if folding in half horizontally, but as you push two of the horizontal folds in together, the diagonal folds need to push out. If you can get one side into an equilateral triangle with the point at the top, the other side will follow suit.

Warnings
