Get the Phoomp mug.
The sound made when a large flat object resting on one straight edge ( eg; a replacement glass windowpane ) falls onto a very flat surface ( such as a table ) and is cushioned by the air caught underneath it. Also the sound of air puffing out of the mouth of the person who let the glass fall, when they realise it has not broken.
