    I think that spring still leaves ambiguity. A very thick, powerful spring like that in an ejection seat could probably get the bowling ball airborne, but wouldn’t actually impart anywhere near the same amount of energy on the marble.

    A small elastic band like that used in a slingshot on the other hand would have difficulty getting the bowling ball to fly at all but could turn the marble into a bullet.
