I hate the trombone episode they did For context I play the trombone

So the myth was that there was this performer who put a firework in his trombone mute and it ended up launching the slide off

They used a crappy pawn shop trombone with no oil to test it

The slide should be so smooth that if you simply hold it upside down and let go of the slide it should fall with near zero resistance

But if your trombone isn’t properly maintained All it takes is one tiny dent to mess that up and significantly increasing the drag

Hell all it would of took is one of the producers to drop it or bump into it to dent it ruining the whole experiment
