I think this is the coolest DIY project I have seen in a very long time. In fact, this has inspired me to start to grow these and make these rain sticks and sell them on my Etsy page. You can buy the seeds HERE. They are heirloom seeds so you can keep the seeds and replant more and more of this gourd every year if you wish.
This project is great for kids to get involved in too. Have them decorate it in any theme they wish. My little boy would probably want a transformer rain stick. See how to make yours at..
