Are tennis balls good for juggling

I am often asked which juggling balls are best. I will review various types of balls to answer as thoroughly as possible:

1) MMX balls – Rubber balls filled with birdseed and closed with a small plug. Comes in 3 sizes. These are like a compromise between rubber balls and beanbags, and are very popular with jugglers. While not my favorite, these are generally good to juggle with and have virtually no bounce. A few times while juggling with them, the plug almost came out of one of the balls. Luckily, pushing the plug back in deeper than before has resolved this. Very durable and pretty squeezable.

2) Sil-X balls – Rubber balls injected with liquid silicon, and has a plug similar to the MMX balls. Popular with many jugglers, these are fine but sometimes feel a bit awkward in my hands. They seem to have a little bit of bounce to them. They wobble a little bit. Durable, and my preferred joggling ball when weather conditions are very wet. The plugs on these things has never come lose. Mine have taken a real beating while joggling outside and seem very durable. They are moderately squeezable.

3) Beanbags – By far the best. This is what I joggle with the most. Often made from leather or imitation leather, sewn together and stuffed with birdseed. They have no bounce and feel perfect in my hands and their weight is just right. Unfortunately, not as durable as the other types of balls and not good to joggle with in wet weather. Very squeezable.

4) Lacrosse balls – Used by some jugglers and jogglers, they have a lot of bounce and are slightly heavy. I don’t recommend them for juggling or joggling. Due to their bounciness some bounce jugglers will use them as cheaper alternatives to more expensive silicon balls. Not squeezable.

5) Hockey balls – Too light to be used for juggling or joggling. Made from very firm plastic and not squeezable at all.

6) Tennis balls – Though they are the right size for most adults, they are too light and bouncy for most forms of juggling. However, you can make a slit in one and stuff it with pennies or birdseed to add some weight to it. Doing this to tennis balls can make them excellent for juggling.(To the right is a photo of a tennis ball stuffed with pennies and covered in duct tape. It weights about 1 lb and is used to help build arm endurance during indoor juggling exercise rather that outside joggling).
