Science Experiment: See how oxygen affects vegetables.
What you need: Zip lock baggy. Two lettuce leaves or two cut celery sticks.

Put one vegetable as is on plate on shelve in your refrigerator. Put one vegetable of the same kind in a plastic zip lock bag, making sure you smush out all the air (oxygen). But don't bruise vegetable! Put the bagged vegetable next to the one that isn't bagged. In a week see how the vegetable in the baggy looks compared to the one that's not in a baggy. Let vegetables stay in refrigerator another week. Now see how vegetables look. The vegetable in the baggy should look fresher.
