The  Scrapa Scrapa Ding Ding  
by Gus
Scotts Mills School

My instrument is called the  Scrapa Scrapa Ding Ding
It’s played by using a coin or a nail. 
You scrape it over the vent or the bell.
I made it with a metal box, an air vent and a bell. 
I cut a hole in the box and screwed the vent and bell with a power  drill.
