Playing with a sink

Playing with a sink could be a dangerous activity. In this abandoned factory, I found two huge metallic sink. Huh, this could be a good strange music instrument. So, I'm knocking it. During this time, two romanian people arrive. They were thinking I was destroying it in aim to steal the aluminum (for us and here in Seraing this is absolutely normal). They said me : be careful, there's photographers just near, its dangerous ! And... they saw the recorder, planted in the sink. They had a look to me and really... I think they understood nothing ! Not destroying the sink ?? But what's this weird guy is doing ?? Probably I was lucky not to be molested. So, here is just two minutes of a stupid guy playing with a sink ; when people arrive, I tidy and hide everything as quickly as I can.
