Devil sticks are long skinny sticks that people use for juggling and performing tricks. They are usually made of a wooden or plastic dowel stick, with two shorter sticks called handsticks.
To play with devil sticks, you hold the handsticks and toss the devil sticks up in the air, then try to catch and balance them on the handsticks. You can do lots of different tricks like tossing them high in the air, rolling them on your body, and weaving them through your arms and legs.
It takes lots of practice to get good at devil sticks, but it's a fun way to learn hand-eye coordination and patience. Plus, it looks really cool when you can do lots of tricks!
