Street Trainers took it in turns to lead each other, eyes closed around the echoey space by making a recognisable animal noise. Photo by John Clare

When I first thought about how to have fun in the streets I thought about scateboarding on handrails. Then I thought about what I do to have fun on the way to school. Sometimes I walk on low walls. We all practised doing this together by walking along white lines in the playground. But this boring so I thought we could could make it more interesting by cartwheeling off the wall at the end.

We tried quite a few of my moves out. We also tried bounding up stairs like an animal.
