In order to prepare healthy drinks, you may need a decent blender. This Chainsaw Blender is quite special though. It lets you blend drinks with a gasoline powered chainsaw. It consists of a 37cc two-stroke chainsaw engine, throttle, kill switch, and motorcycle handlebars.
You should be able to use any standard blender for this project. Of course, you are going to need an engine and a few motorcycle parts to get started. mikeasaurus has shared more information on Instructables.
