it's a design for a glider that will amaze you cause when built correctly it can actually fly over a distance of 30 feet easily.
the pictures below show a front view and a back view of the finished glider.
Step 1: Materials
1 A4 sized paper ( preferably a blank print paper, those are good)
1 ruler of 30 cm ( 1 feet )
OK, got those, let's start folding
Step 2: The Beginning of the Folding
pic 1: take your paper
pic 2: fold the long end in 2 so you get 2 rectangular sides who are identical to eachother
pic 3: fold a triaglurar from the top to the middle line so you get what's on the pic
pic 4: now do it again but from the other side
pic 5: now fold that triangle you get at the top of your paper in towards the other side of the paper over those folds
Step 3: The End of the Folding
just a warning you might have to use math in this step
again can't really tell what you have to do so just follow the pictures
pic 1: fold those 2 triangles again and make sure that the tips meat eachother at the tip of the big triangle
pic 2: now close the middle fold and you should get something like this
pic 3: now for the math: the lines should be at 1/5th of the end so mine is 10,5 cm so 1/5th of 10,5 is 2,1 cm
pic 4: now fold at those lines so you get something like this
pic 5: do it again on the other side so you get the end product
Step 4: Final Step: the Finetuning
on pic 1 if you see those gaps across your plane you'll need to mess a little with the outer wings so those gaps are gone cause those make your plane crash instead of gliding.
also on pic 1 if at the end your wing are like this --_ you'll again need to mess a little with it otherwise the plane will not stop spinning
on pic 2 u see that at the end of the plane u have a kind of u form you'll have to check those gaps at the middle of the plane and again mess a little with those to make the wings go completly straight
Step 5: The Video
it only shows 3 flights but i'll shoot some more later.
