Waterbomb Base
Like most people who are new to oragami and paper planes, I had no idea how to make a waterbomb base. After searching around, I found out how to make it and wanted to share it with other people who might have been like me. A waterbomb base is a certain fold used in intermediate to advanced oragami and paper planes. It takes one standard piece of printer paper, although many oragami projects need a square piece of paper.
First Step
Fold one corner as far as you can, then the other. For a square piece of paper it will bring you to the opposite corner.
Second Step
Fold vertically, unfold, then fold horizontally and unfold.
Third Step
Fold diagonally on your earlier creases.
Forth Step
This is the hard part. It's a little hard to explain, so refer to the pictures. You have to pinch the crease in the pictures and smooth it out evenly.
Done!
You're done! An endless supply of oragami awaits you! Congratulations!
