Coffee Beans Falling into Hopper

So I’ve set up the beans and they work well with their physics but I am trying to make a hollow cylinder “bowl” for them to fall into but I cant seem to set any collision bound that will let the beans fall into the bowl; they always seem to rest on top. Is there something I am am missing? I searched and didn’t find anything but maybe I looked over something. If anyone could point me to how to accomplish this it would be greatly appreciated!

Posted in the wrong section, can this be deleted? I already posted in the right section.

Oh, so are you using particles or individual physics meshes in the game engine? Also try recalculating the normals of the bowl and make sure it is a collision object.
