Nice homemade wind turbine

Posted on July 12, 2016 by robertwilkie

This could be a nice build to do with kids.  I was surpised how “easy” the author build the vanes.  Me, I would have to print out a template to do it. http://www.instructables.com/id/How-to-Make-Small-Wind-Turbine-Homemade/?ALLSTEPS

Nice simple and small cotton candy machien build.  Good write up too, but…I am not so sure about using a plastic bowl for the outside with an open flame nearby.  I would switch to metal just in case. http://www.instructables.com/id/DIY-Cotton-Candy-Machine/?ALLSTEPS
