Dual-task bicycle

on March 24, 2009

Recently, I stopped by the Edible Schoolyard, a garden and kitchen classroom at Martin Luther King, Jr. Middle School in Berkeley. Here, students learn how to garden and find out about where we get our daily food. As part of this project, they’ve built a wheat-grinder out of an exercise bicycle. Kids can get on and ride while grinding the wheat for their homemade pizza crust at the same time. Here are some photos I took:

The wheat berries go into the white container and funnel through as someone pedals
