Watching YouTube celebrity ‘engineerguy’ (aka Bill Hammack) explain the engineering behind a gadget is far more entertaining than books or school could be. And this time even more so because he breaks down the simple but clever design that allows a Nerf blaster to fire one dart at a time.
You probably don’t give much thought to how the Nerf blaster in your hand works while you fire away at annoyed co-workers, but take a few minutes to watch this video and you’ll have a better appreciation for what is actually quite a marvel of plastic engineering. And that’s just one of the most basic Nerf blasters he’s taken apart. Imagine the engineering that goes into something like this. [YouTube]
