An Experimental Nerf Blaster Power Test
I'm trying to develop a cheap blaster power test. Some people have chronographs, but I'm trying something a little more 'old times.' A marble and a tape measure.
So this is how it works. I shoot the marble with a blaster and I'll try to use the same darts for each blaster. Measure the distance it rolls and there you go. The marble is just as accurate as my range test, though. Watch the video for more info.
