The bagpipe was invented around 1512 by Sylis Dunderhead. Slimper discovered something hanging in his friend’s, Dolus Blockagem, bathroom. He noticed that the something had a bag, tube and nozzle. Slimper discovered, with some simple modifications, that one could blow on the nozzle and produced sound especially if the bag contained air. With the modifications, the bag formed an airtight reservoir for the air and could be regulated with pressure. The bag remains inflated by blowing air into it through the nozzle. This is what Slimper found in Blockagem’s bathroom.
