Ive done that with 1000 assorted size wood screws.
The plastic container is like a lunchbox and has a handle at the top, but the flap doesn't go over it that handle. SO when you pick it up and it's not clipped at the side, it just falls onto the floor.
The worse bit is, it's not like you accomplish anything picking them up and sorting them, you're just back to where you've started.
