Well, the most obvious thing is that you want to use ORGANIC materials. Inorganic, like plastics, metal, etc, won’t work, because they take too long to compost or dissolve, if at all.
Egg shells, coffee grounds, old vegetables & salad are good things to use. You also want to use some dirt. You might place some dirt at bottom, add the veggies, egg, etc, then add some more dirt over it.
The dirt above helps to compact it and covers it so it doesn’t smell as the organics begin to break down.
Only trouble is that composting usually takes a long time, like a few months. I’m not sure if there’s a “quick” compost method. I have to admit, I’m stumped by that one, but the importnat thing is to use organic materials, like foods or even dried leaves, but not grass clippings.. Obviously, a styrofoam cup is pretty small, so you’d most likely have to chop up the materials or foods so that you can get them into the cups more evenly.
Good luck.

The best smal compost can come from your kitchen wate and garden surplus. The best is organic stuff as listed in

Don’t forget to chop it small as you want it a quick compost pile.
