Last month, expert pole vaulter Allison Stokke attached a GoPro to her body and gave us this dizzying yet magical footage. Now, Ringling Bros’ Circus XTREME performer Gemma Kirby — who at 25 years old is the youngest female cannonball in the world — has strapped on a GoPro to show us what it’s like to be shot out of a cannon at nearly 60mph. The whole thing’s pretty thrilling; plus, you can’t help but feel a little antsy when you hear Kirby take deep breaths as the crowd counts down to the big moment.
