You will need:
Foil to line inside of basket
wheat berry seed (this can be found at your local health food store in the bulk section) or you can order here.
Spray bottle of water
Soaking the wheat berries the night before you plant will speed up the germination. Make sure you keep your basket in a sunny window and keep the seeds moist. You should see sprouts within a few days and have long grass within two weeks. The grass is edible so feel free to trim it and add to a green smoothie.
Observe your grass as it grows. Measure the blades if you like. Notice droplets of water that collect at the end of the blades. FYI, jelly beans don't do well in a real grass basket.
