The guy looks to have an apron on, so I would presume there is dust about, the round things he is hitting are a few on top of each other, is it something to do with flaky pastry????

Sorry Gloria no. Totally non-edible. (You're right about the apron though.....)

Saggar maker's bottom knocking?

Amazing! You've done it again Kev! Correct.
Now we need another object.
