Continuity mistake: Jamie and Adam are shooting at Police badges to see which one would potentially stop a bullet. When they get to the third badge, it is held up to the camera. It says 'Jamie Hyneman' on the badge. The badge is then shot, and shown again to the camera. This time the engraved writing on the badge has changed to 'Adam Savage'.

Revealing mistake: When Jamie sits down after rappelling down the canyon wall you can see that he has climbing rope attached to his harness. It's wrapped in duct tape to look like its the rope he and Adam made of duct tape. This may just be a safety line to support his weight if he duct tape rope snaps, but the Mythbusters usually point out any backup safety systems and explain that they are there for caution and don't contribute to the test. (This was explained in the aftershow. It was a safety line required by the shows insurers).

Question: When the Myth Busters were testing whether higher ground does give you a huge advantage in sword fighting. Adam and Jamie do the sword fighting themselves, then they ask a sword fighting expert to train them. Why didn't they ask skilled sword fighters to do the fighting instead? It would have been much to easier to determine whether higher ground gives you an advantage by asking experts to do the fighting. Did it actually make sense to ask an expert train them instead of asking experts to do the fighting? If so why?
Question: Couldn't Adam, and Jamie have made ten magnets with the same diameter, but much longer than the other ten circular magnets they used? Those type of magnets would be able to contain a lot more energy, and generate more pull than the circular ones they used.
