Only one way out

The conveyor belt starts to move as you rise up you find that the coveyor belt is covered by a plastic case which only allows you to crawl on your knees. The area around you looks like a factory of some kind. You try to crawl back from where you came but the further back you go the faster the conveyor belt moves. Without warning the conveyor belt drops you into a large bowl. The bowl must be on somekind of conveyor belt too because it starts moving as well. Suddenly you hear a shrieking noise. As fast as it came it goes right away and everything stops and gets very quiet.
