Myth Busters missed a good one. Could a bullet do a 180 passed an mri machine.

I don't think Mythbusters had the budget to deal with a possible result of "bullet gets sucked directly into the insanely expensive machinery, destroying it"

I suspect "MRI-strength electromagnet" falls into a different budget category than "medical grade and certified imaging system", including but not limited to "MRI removed from hospital and junked because it's no longer maintained / useful / accurate enough". They are pretty resourceful

Plus the danger of fluid helium escaping within seconds.

You could probably get them to do a 180-degree u-turn

Might be fun to calculate it on paper if I weren't so lazy.

Finally, something that can curve a bullet.
