This is a fun glider that I invented while "free folding" some paper airplanes. I was very impressed by its performance, but the greatest thing about it is that it gives off a fun little from its wings just after being thrown.
Step 1: 1st Crease
Take a piece of printer paper (alliteration!) and fold it in half lengthwise to create a crease down the middle.
Step 2: Special Fold
Fold a top corner down to meet a crease, but do it so there is about a 1/2 inch space between the top of the crease and the center crease like shown in the picture. Do the same for the other corner.
Step 3: Fold Down
Fold the top over like so.
Step 4: Create Point
Fold the corners down to line up with the center crease like so.
Step 5: Fold in Half
Gold the whole thing in half like so.
Step 6: Wings
Fold wings down. Make sure they line up evenly.
Step 7: Second Pair of Wings
Flip he plane over and you'll find two little flaps sticking out to the sides of the center. Fold these each in half like shown in the pictures.
Step 8: Throw!
Hold the glider as shown in the picture and give it a decently hard throw. Notice as it leaves your hands, the wings do a little flap and slightly boost the plane upward. The plane then coasts slowly to a gentle landing. Thank you for checking out my instructable! Please give any suggestions in the comments. Have fun!
