Inspired by one rather inventive trombone player, we decided to take a look over on YouTube to see whether other users were discovering, er, interesting uses for their GoPro cameras.
They've taken GoPros to pumpkins, to swords, to high school bands, to the front of a rollercoaster and even soared it near fireworks.
Take a look through the video gallery above for all this and more. Share in the comments below any weird, wacky and wonderful GoPro clips you've seen online.
