I require ideas for a biological (organelle) carnival game.?

This game should properly identify the functions and structure of the CHLOROPLASTS of a cell. This carnival game should be playable by peers.

The ideas I have currently may or may not be good, but I'd like some opinions on them.

¥ Ring Toss

We set up a few green bottles to act as the "stands" to hold up the stuff within the chloroplast; the "rings" will be green, simulating the ring-like structures within the chloroplast.

I'm not sure how to illustrate the function of the chloroplast with this game.

¥ Into the Pumpkin

We thaw out a pumpkin, which simulates a chloroplast's outer membrane. We have our peers throw items (green) into the pumpkin to simulate the internal structure of the chloroplast. Once again, I'm unsure on how to properly illustrate the chloroplast's function within this game.

Perhaps someone on Y!A will be of help.

Otherwise, this question, and myself, will be lonely.
