Everyone knows the finale of Breaking Bad was awesome. But was it accurate? That’s what the guys at Mythbusters set out to determine.

The pair recreated Walter White’s infamous machine-gun surprise to see if creating such a device was feasible. And Breaking Bad creator Vince Gilligan was on hand to witness the experiment.

So, how did things turn out? See for yourself.

If you are unfortunate enough to have missed Breaking Bad when it originally aired, and want a frame of reference, you can watch the clip below. However, I strongly advise against it, and suggest you go back and watch the whole series.
