We did this as kids: catch flies in a bottle trap, put them in the fridge to slow them down, crazy glue a long narrow strip of single ply toilet paper to them, then let them warm up and fly around with their "banners". Often the strip would be too heavy and the fly would buzz along the ground so you'd have to snip off enough of the paper until the fly could become airborne.
I was extremely sensitive as a kid about all sorts of things and this was certainly at least unkind to the flies but for some reason it didn't bother me.

You give love a bad name
Now that tune is stuck in my head. And now it's probably in yours too.
My sincere apologies.
