Coloured bubble chamber photograph from CERN. A positive kaon, coming from the top, decays near the centre into three pions. Two are positive pions which curve clockwise in the bubble chamber's magnetic field, towards bottom right & top left. Each decays into a positive muon which decays in turn into a positron that forms a spiral track. The third, negative pion describes a shallow anticlockwise curve downwards before decaying to a negative muon. The other tracks are not part of this event.
