We all have to be aware of wasting energy,and this Instructable was forwarded to show you how to save energy by using throw-away plastic bottles. There is a lot of raw plastic materials being not recycled. It just goes into a garbage pile . I have used plastic drink bottles for whirligigs and also old CD discs which are also re-cyclable.The resulting devices I use in the garden or my trees as ornaments that twist and rotate in the wind.
THIS INSTRUCTABLE WILL BE ENTERED IN THE US OF EFFICIENCY CONTEST. So vote.
Step 1: Parts and layout
1-A couple of old cd discs can be used or any round piece of plastic about 1/32 thick.
Beverage bottles- I used a water bottle about 2 inches diameter and 8 inches long after cutting off the top . A scissors can easily cut down the length .I used a strong shears for cutting the bottom.
Best string is a 1mm dia.plastic cord I found in an craft store for under a dollar. It should be stretchable. Stretchable string gives a counter-rotation after the wind winds -up the string and stops.
Glue can be hotmelt but I used Goop Glue. It is slow in cure [one hour] but very strong. I also use fish line illustrated here.
Step 2: Preparing
This is a general description of the Step . The bottle should have the top cut off. I used a pocket knife. Clear adhesive tape also helps locate the bottom 1/2 bottle on the cd disk.Apply glue liberally.
