One of our Farm to School purchases was a bike blender attachment. A regular bike gets hooked up to a stand and a platform with a Vitamix blender. Thirty seconds of pedal power, and you have a full pitcher of smoothie.
We ordered the smoothie apparatus in order to promote healthy snacks at school events. The mountain bike club borrowed the equipment last weekend for the elementary cross-country meet. We used a simple recipe of apple juice, frozen berries, fresh bananas, and ice. Not only did we raise money for our team, but we also had the pleasure of passing out healthy, delicious drinks to kids running their hearts out on a beautiful day in Julian.
Thanks to my Dad who first saw this type of bike at a golf tournament and led me to research it. Find out more at http://www.rockthebike.com
