The Hammer is a mean flying machine. Don’t let its small size fool you. It’s fast and tough and will destroy any plane it comes in contact with.
Step 1: Start with a regular piece of rectangle paper that’s 8.5 x 11.0 inches (215.9 x 279.4 mm).
Step 2: Fold the top right corner to the left edge as shown.
Step 3: Unfold.
Step 4: Now fold the top left corner to the right edge as shown.
Step 5: Unfold.
Step 6: Fold the right edge along the diagonal crease indicated by the red line.
Step 7: Do the same for the left edge.
Step 8: Fold the left half to the right.
Step 9: Unfold.
Step 10: The triangle flap inside most likely remained folded to the left. Fold it back to the right.
Step 11: Fold the very top edge down to the bottom edge. In other words, fold the top half down.
Step 12: Let’s create “new creases” that we can use. Fold the top two corners to the center of the X crease indicated by the black arrow.
Step 13: Unfold.
Step 14: Fold the top flap up at the red arrows where its edges meet the “new creases”.
Step 15: Fold the left and right diagonal edges to the “new creases”.
Step 16: Fold in diagonally one more time at the “new creases”.
Step 17: Fold the top part down as shown.
Step 18: Turn the paper over.
Step 19: Fold the left half to the right.
Step 20: Make the wings by folding the right edge to the left edge indicated by the black arrow.
Step 21: Turn the paper over.
Step 22: Now fold the second wing to line up with the first wing.
Step 23: Open the wings. All done! Now let’s learn how to fly the Hammer right.
Step 24: When unfolding the wings, make sure they are tilted up a bit like this so the plane can fly well.
Step 25: Hold this part of the plane and aim it slightly up so it can fly far. Now throw it hard!
