Grass.

Below is a picture of the project we're working on currently. I found the idea of growing rye grass in little containers and then decorating them with faces (aka chia pet wanna-be but way better) in a magazine. The teacher liked the idea. We decided to grow them first and then decorate them later. :) It's amazing. We did this project on Friday, and within a week they're already nice and tall, ready for a trim. :)
