Introduction: K'nex Back Scratcher

This is a very simple and useful back scratcher that is easy to make and even has an adjustable arm.

Step 1: Materials

The materials are easy and short so just refer to the picture instead.

Step 2: Making the Scratcher Head

The scratcher head is very simple, and to start it off, connect the triangle connectors to the short white rods. After that is done, use the middle peg to attach them all to the yellow rod.

Step 3: Making the Body

Take the 2 long rods and connect them firmly with the ladder connecters (orange Rectangles) Then attach the scratcher head made in the last step.

Step 4: Make the Adjuster

To make the adjuster, start by sliding the last gray rod down until it reaches the middle ladder. Then use the 2 tan stoppers to make the rod firm in place so it will not spin while you are scratching. If you every want to adjust it just slide the middle ladder to make it shorter or longer.
