I've just finished watching an episode of Mythbusters where they tested another MacGyverism. This time from the Wish-child episode when MacGyver uses the gunpowder from bullets to blow the lock of the ships door open.
Unfortunately I had no idea they where testing it in this episode so wasn't set up to record it and there aren't any clips of it on youtube, there however some clips and excerpts on
Discovory's video site hereInterestingly they found that the MacGyverism is mostly plausible with the exception that the amount of gun powder from the 6 bullets he used in the episode isn't enough to blow the lock (it gives a nice little explosive display but that's it) and also they found that you can't actually pull bullets apart with your hands like he did in the episode.
So everything in the MacGyverism actually works as we see it happen, but the end result is exaggerated.
Was also good to hear them talking up MacGyver as the second greatest show on Television (the first of coarse being their own show - in their opinion anyway

)
Watch some clips of this MacGyverism being tested
