Final Action Division B

[SciOLYrulez]

Hello! According to the Division B rulebook, "Final Action:
i. After all other planned scorable actions have been attempted, the Device must separate the
original mixture into three separate (marked by material) containers that are different from
the original container where the mixture was dropped.
ii. After the last material reaches its container, the Device must ring a clearly audible bell to
mark the end of the final task completion and the end of timing.
iii. Points will be awarded for each item from the original mixture that is in the correct marked
container when the Device stops. Points will be deducted for each incorrect item from the
original mixture that is in the wrong container. Bonus points will be awarded for each of the 3
marked containers that contain all 10 of the correct original items and no other original items.
iv. Team members will not be allowed to touch any of the original 30 items during Device operation."
However, I have been struggling to make this work and I do not understand it. I would appreciate ideas on how to sort them. In addition, how do you get the bell to be rung?
