Every good experiment starts with a question and a hypohethesis. That's the scientific method! So here's to The Slow Mo Guys for posing this important question:
Question: On a scale of "ow" to "OWWWWWW," just how painful would it be for a human arm to come into contact with a chain reaction of 150 mousetraps?
Hypothesis: It would be pretty painful.
Just check out the video above (top) to see the whole procedure in super slow-motion.
And if you'd like to know more about the physics of mousetraps, see Drexel University's helpful mousetrap page.
