My physics calss is making a machine to pick up a washer and put it in a cup, any ideas?

it has to be at lest 4 simple machines, with no electricity. high school physics class.My physics calss is making a machine to pick up a washer and put it in a cup, any ideas?
Well i would use a falling weight running through a pulley(1) to pass a magnet over the washer(use the surface the magnet is following to keep the two seperated a bit). The magnet can be mounted to the bottom of a car with wheels and axels(2). Once picked up it can follow an inclined plane(3) up to the just over the cup where the magnet and washer will be seperated from each other by the track forming a wedge(4) between them.





Some questions. Does the washer sit on the table or can you have it up on something so you can get under it? Do you get more points for simplicity or for haveing more simple machines??My physics calss is making a machine to pick up a washer and put it in a cup, any ideas?
a movable magnet behind an aluminum shield is a great way to get around the electricity problem, at least for picking it up and dropping it.
It has to be a Rube Goldberg Machine. It has to have at least 4 simple machines. We can't touch it more than the initial move to start it. It has to pick up and move a waher at least 6cm and drop it into a cup. It can't use electricity but it can use a magnet
