Reflecting on this mistake I will make a different way of sorting the marbles, perhaps I should try magnetism.I think that magnetism could be more persistent way of sorting my marbles from my rocks. Though the marshmallows float as expected.

this desine had a huge mistake. the rocks were cloging up were the marbles were suposed to go.

Second Design Solution-
This design has a huge mistake. The rocks were cloging up the holes were the
marbles are suposed to go.



Initial Design Solution
First Draft of a Design Reflection- Results

I never tested this design becuase I realized it was to complicated. The pulley systems and the movement of the pulleys was too hard to build. Therefore, I have developed another design I think completes this challenge.
