This is a very cool star and frisbee that transforms. (This is not my work but I just want to make everybody know about it. The first pic is the star and second frisbee.
Step 1: Folding
Either buy origami paper, you can get it at Michaels, or cut eight pieces of square paper, any size. I didn't have any more origami paper, so I unfolded my star, so the folds are already made. Use the video if I didn't explain good enough for you.
1. Fold the top edge of the square paper down towards you. The open ends should be facing you.
Step 2: Folding
Take the top right corner of the horizontally folded square and fold it down to the open edges.
Step 3: Folding
Unfold step 2. No picture is needed.
Step 4: Folding
Hold the paper as shown in the first picture. At the top right corner, start pushing down. You should end up with the second picture. Finish pushing and then crease. It should have two open flaps.
Step 5: Folding
Unfold to a square again. Take the top left and bottom left edges and fold them into the center crease, as if you were making a paper airplane (see picture 2). Lastly, follow the picture notes.
Step 6: Making more
Make seven more of the polygons (step 1-5.) You should end up with eight. Almost finished! Yay!
Step 7: Making the frisbee/star
Follow the pictures and picture notes. After you have connected the first two, keep joining them in the same way. The last piece is the hardest to get in, but still is easy.
Step 8: Transforming!
To transform, hold two opposite sides and pull gently. (see video).
When in frisbee form, you can throw it, but don't throw it very fast. Also be gentle with it.
