A colorful outdoor kinetic yard sculpture made by cutting single-direction spiral ribbons down a painted plastic bottle that twirls in the breeze.
-
Paint vertical stripes of vibrant outdoor acrylic paint (magenta, turquoise, yellow, lime) down the length of a smooth 1-liter plastic bottle.
-
Once the paint is dry, cut off the bottom base of the bottle with scissors.
-
Starting from the bottom cut, use scissors to cut a continuous, uniform 1/2-inch wide spiral ribbon winding up toward the bottle neck.
-
Gently pull the spiral downward to stretch the plastic into an elongated spring.
-
Thread a piece of fishing line or nylon cord through a small hole in the top bottle cap, attaching a metal swivel hook.
-
Hang the spinner from a patio rafter or garden tree branch; when the wind catches the spiral, it spins and creates a colorful optical illusion.
