I found this in my closet while cleaning it out. No one knows what it is

You only need three items:

A metal coat hanger wire (cut and shaped into a coil)

A rubber band (for tension)

A small washer or bead (to add weight and “rattle”)

Steps:

Bend the wire into a tight spiral with a straight tail.

Loop the rubber band around the coil and anchor it to the tail.

Place the washer at the tip for extra momentum.

Fold flat and insert into an envelope, securing the tail under the flap.

📌 Pro tip: Test it on yourself first!
