Via the blog Make comes another way to spin something delicious. A while back we covered the Blender Bike and now comes the cotton candy bike. Riding around with a propane tank attached to my bike might make me a little nervous, but it’s nice to see yet another example of pedal power. From the blog entry . . .
Kai took these photos in southern China in 2006, the sugar is heated with propane but the cotton candy is spun using the bike pedals.
