as the tool tips talk about you can use small stones or snowballs to distract zombies. but for the most part stones won't be something your going to carry around more so when your not using stone tools/weapons. and snowballs are location specific if your in the desert or anywhere but the snow biome your not going to have snowballs. so why not give more options. Cans filled with stones could make a great noise maker (and be a useful trap to alert you of zombies or other sneaky foes) if you got gunpowder or maybe black powder (early gunpowder) make fire crackers like dying light. or small elcetric noise makers as more final teir distraction.
