Recycling slot machine

My local authority used to have something on its website about how our recycling was sorted. So, shredders cut things up, magnets lift out ferrous stuff, eddy currents push non-ferrous metals off the conveyer, blowers take paper away, different grade plastics are floated off in different salinities of water, etc. - it all sounds amazing. This idea is to have a massive slot machine where people can put their recycling in and watch it be shredded and sorted.

In principle, this is exactly the same as those charity collection boxes which children like putting money in because the coin can be seen spiralling down a funnel, or clacking its way down a complicated path.
