My grass is too plush to be able to 'walk' a can like that, and it's illegal to use the street here. However, I may try something similar with a piece of floating wood the next time I'm down at the water. Might be fun to 'walk' a block of wood out to a mooring bouy ... and I imagine calm water will be very unforgiving in displaying misses for all to see.
Eventually, I'm going to have to consider a proper digital camera, so I can record and post videos.
