I will show you how to make a glider dart plane. It is pretty simple.
Step 1: Materials
You don't need very much to make this.
1. one piece 8.5" by 11" paper
2. one 7cm piece of tape
3. a pair of scissors
4. your hands
Step 2: First Folds
First fold the piece of paper in half. Then you fold it into quarters. Next, you fold the right then the left top corners to make a fold from the top of the middle fold to the bottom corner.
Step 3: Second Folds
Now fold the left corner over to the right diagonal fold. Make sure you pull it a bit tighter to the right to make the plane's bottom have a "v" shape as seen in picture 2. Then once you have folded like so in picture 3 you fold the extra paper that is over the edge under the plane. After you have folded the extra under fold it over again then tape it.
Step 4: Finishing and Throwing
Now you will need you tape. Put only half of the tape on top of the plane where the "v" part is as seen i picture 2. Next fold the tape in half under like picture 3. Now cut a "v" in the tape about a millimeter away from the paper "v" as seen in picture 4. Now is the throwing part. Put your index fingertip in the taped "v" like in picture 5. While you have your fingertip in the "v" grab the edges of the plane with your thumb and your middle finger like in pictures 6 and 7. Now just throw it hard at a 45 degree angle into the air.
