This is my first Instructable so bear with me OK.
Recently my friend made this airplane up and it flew so well that I just had to share it with everyone. He used different techniques than I do. Somehow his flies better than the ones I make. I think this happens in the steps where you make the waterbomb base (the triangle). He doesn't fold back like I show. Instead he just pulls the paper together into the base, then creases it.
Step 1: Materials
Start with a regular sheet of 8.5 X 11 paper.
Step 2: Fold 1
Fold one corner down, then unfold.
Step 3: Fold 2
Fold the other corner down, then unfold.
Step 4: Fold 3
Optional: Flip paper over and fold like shown. If you cannot see where to fold look at the second picture for help.
Then unfold and flip over.
Step 5: Fold 4
Press down in the center and flatten to form a triangle.
Step 6: Waterbomb Base
Now we are going to form the waterbomb base as it is called in origami.
Step 7: Fold 5
First fold the triangle's corners to the top.
Step 8: Fold 6
Fold up the bottom corners of the square like shown.
Then unfold to form the triangle again.
Step 9: Fold 7
Fold back on the first crease.
Step 10: Fold 8
Fold both corners down over the paper.
Fold up the rest of the way.
Step 11: Fold 9
Fold the tip down.
The second picture shows a close-up on the pocket that has been made for the next step.
Step 12: Fold 10
Tuck the flaps into the pocket.
Step 13: Fold 11
Fold in half.
Step 14: Fold 12
Fold wings down as shown.
Step 15: Fold 13
Fold the fins.
Step 16: Flying
Before flying shape the paper airplane as shown in the first picture.
When flying this paper airplane there isn't really a set hardness you have to throw this plane. Some that I've made need to be thrown hard, others not so hard.
