The Sound Of Flushing

My eldest son Max is 21 and he has had an obsession with water his entire life.He is constantly shouting for the toilet to be flushed whether anyone has even used the toilet or not.  This is the absolute bane of our life but I had a brainwave a while back and decided to record the sound of a toilet flushing.  It has actually worked and I'm continuing to stand outside the room where he is each evening, and managing to convince him that I'm flushing the loo.  Read on, I love it when a plan comes together!
