This is a really easy flying saucer that really floats a little bit if you spin it in the air kind of like a frisbee, but not try to throw it.
Step 1: Beginning
Fold your paper (it needs to be big) in half both ways.
Step 2: Fold Corners
Fold all the corners into the middle and flip the paper over.
Step 3: Fold OTHER Corners to the Middle
... Fold the other corners to the middle
Step 4: Fold (little)
Fold all the inside corners a little ways to the middle. It doesn't matter how far, just make sure they are all equal. Make them stick straight up.
Step 5: Fold
Fold the corners to the edges of the little corners and unfold them a little bit. Flip over.
Step 6: Again...
Just like before, fold the inside corners out a little bit. Again, make sure they are all even.
Step 7: Finished
Good job! To make it fly, spin it in the air.
