Just buy some tennis balls, they are cheaper and pretty easy to get the handling down with them.

I did 4 balls 3 times in a row last night, go me!!!!!!!!!

Tennis balls are okay, once you learn how. They're pretty tough at first as they don't have enough weight to handle well, especially if you're just learning.

I've heard of people slitting tennis balls along the seam and filling them, either with birdseed, rice, or sand and then gluing the seam closed again.

DaveV said it, but I just have one thing to add. All the things listed will work, but the bird seed is the best choice. Juggling balls that you buy for 8 bucks apiece are usually filled with millet.

I can juggle four revolvers. I'm not too great at juggling though, but when I do juggle revolvers it always gets my audience really emotional.

Only 3 .

2 throwing knifes. and i am happy with that.

Are they actual knives, like the sharp kind, or are they juggling knives?

Real knives; I only deal with the real thing. I collect knives so I have learned how to throw, fight, juggle, balance, even make my own.

Yes i have caught them wrong before.

did you cut yourself?

What do you think
When you work with knives your bound to cut your self.
Throwin' and catchin' them isnt the safest thing in the world.

Well, like big cuts. Like the ones that bleed for ever and leave a nasty scar.

One time I was doing magic and juggling, and I had a guy who thought he knew everything, and just had to say everything he was thinking and be as rude as possible, so I loaded my revolvers with blanks and scared the crap out of him.

Niiiiiiiice!
