The YouTuber released a video on his channel showing the dart traveling “2.3 times the speed of sound at standard conditions.” Watch the video below:
He estimated the speed of the NERF dart to be 800 meters per second, which would be Mach 1. But, he is not planning to stop at just breaking the sound barrier. “I’m planning to make a version two of this cannon. I have a couple of ideas to make it even faster,” said Giaco.
