Just time between the showers today to pedal your own free smoothie at the final day of the Fair Trade Festival (right) in Potters Fields, right underneath Tower Bridge.
The blender-bike here comes from Kitchen Academy, who provide mobile cooking services at various events. So if you want a bike-powered drinks generator for your own event, you know where to go.
The Fair Trade festival offers a range of activities highlighting the organisation's activities, such as Hook-a-Banana (like hook a duck, only more equitable) and banana jousting (so you can have fight after one too many at the bar and still get one of your five a day). And various free samples. Which is fair enough.
