So poi.

Really simple to build your own.

They're a lot of fun and really cheap to make.

Step 1: String and ball

Picture of String and ball
Start with finding a good piece of string. I found mine in the basement, it's a synthetic string that might have been for clothing line or something. Just make sure it doesn't break.

For the weight I use a tennis ball. Just the right weight, cheap and easy to find. I wiggled a screwdriver through to make the holes. Make sure the holes are opposite or it will wobble. I used thin metal wire to get the string through the ball. A metal washer or two makes sure that the knot doesn't eat through the holes.

Hey, these are really well thought out! Good job! I just plonked some spare juggling balls in the ends of some fluro-orange stockings, works a treat! You can adjust the length of them by wrapping them round your hands a bit more... These are a much more credible attempt though :-P
After you master Poi, you should light it on fire, it would be pretty fun :)

Sure! Fire poi are great!

Not too good with strings and tennis balls at that point though ;-)
What does it do?

They are for spinning! It's a juggling technique. Try it, it's lots of fun! Not very hard to get started.
