Many mirrorless cameras shoot 30-60 images per second. Nikon J1, V1, and many of the sony mirrorless accomplish this within electronic shutter - its nothing new ;-)

As has been stated, use a bowl, or like I do - a hide if you're at home, a hat if you're in the field, or your hands if you are using a small snake or a particular snake on location. In the field my hat is used for large snakes, hands for not so bitey snakes, and a lens cap for tiny snakes. Give them 2-5 minutes to settle, get your camera set up and take some "test" shots of the bowl / hide. Get the lighting how you want it. When you are ready lift and fire.

Note: Works best when you use a tripod and remote release. At the least a tripod so you can just tap the shutter button.

Side Note: 30 FPS shooting does not promise clear shots. Motion blur is your enemy and your limitation is purely shutter SPEED. The actual exposure value, you can shoot 30 FPS but if you shoot at 1/60 of a second exposure wise, you will still hit an issue with a moving subject.
