the favorite of girls and boys!

Step 1:

All you need to make a paper Slinky is a bunch of 1:2 rectangle pieces of paper. Just incase you forgot, a 1:2 rectangle is easiest obtained by cutting a square pieces of paper in half. You can use as many pieces as you want to make a longer Slinky but I suggest using at least 20 units to make a model that will slink the best. 

Step 2:

Fold the paper in half hot dog style and unfold.

Fold the edges to the middle crease made in the previous step.

Fold in half hamburger style then unfold.

Fold the edges to the middle crease made in the previous step. Look at the last picture in this step, make sure the creased side is on the outside and the split side is on the inside. 

Step 3:

Flip the unit over and fold hot dog style so that the unit looks like the third picture. 

Now's the tricky part. Pull up the right side so it's makes a 90 degree angle with the rest of the unit. The crease that used to be the edge will line up with the top and a triangle will form at the joint.

Pull up the left side and crease, making sure the crease lines up just like the right side. 

That's one unit, now make about 19 more and meet me over at Step 4.

Step 4:

To connect the units, open the pockets up a bit as shown in the first picture. Insert the closed ends of another unit to form a ring shape. Now open the end of the hit you just added and add a third unit. Continue adding units like this until they're all attached.
