Well, this instructable will show you how to make your very own rainstick that is lightweight and uses common materials laying around the house. This build is extremely easy to tweak your rainstick however you want.
I have been making these ever since elementary school, they are extremely versatile and great for kids to make on their own.
Video of how the rainstick sounds is on the last page.
Step 1: What you need
1 screwdriver, either hand powered or electric (I used electric since its much MUCH easier and quicker)
1 fabric cardboard tube (see below)
a bunch of screws
Something to make the sound (I used a little more than a half pound of lentils on this rainstick, but by all means, experiment with different materials. Pea gravel works extremely well.)\
Total Cost: around $3.00. (.25 for the tube and half of a $5 tub of screws)
Compare that to a $40 rainstick of the same size.
