Chocolate fountains require a good deal of work

My class planned/hosted the school prom this year, and we decided to get a chocolate fountain. That was all well and good in the beginning - it was assembled easily and started working, just as expected. 

The problems appeared at teardown time. You see, the largest dish of the fountain was fixed to the main part. Therefore, the only way to remove the chocolate from it was to very carefully place the whole assembly in a sink and direct the water to avoid the electrical parts.

Even after twenty of fiddling around, the device is still not completely chocolate-free, and will probably need to be left with water in the bowl to get the last pieces off.
