I wanted to perform the zombie ball without the cloth(yes there is a way)
Um, yeah........ that would be called the Okito Floating Ball or the Don Wayne Floating Ball . Zombie with no cloth is pointless.
Don't be fooled into thinking that they won't see "it" just because you are wearing dark clothing and performing against a black backdrop .
A stray beam of light or a flash from a camera is all it will take to bring disaster. You would need to have total control of the lighting over the stage area and the audience area to pull this off , and it would probably be too dim to really see much .
If you have enough control over the lighting in this situation to attempt a black art Zombie then you certainly have enough control over the lighting to do the Don Wayne or Okito floating ball.
There is a quickie way to adapt a zombie ball into an Okito style ball at the end of the book Further Tips on Zombie by Neil Foster and Joe Karson (published by Abbott's Magic Co. , do a Google Search . Some other dealers stock the book Further Tips on Zombie . )
i'm not sure how big the ball is and if you can see it from far away
Morrisey Magic makes a 5.5 " inch diameter Zombie ball. Very visible.
The previously mentioned Don Wayne Floating Ball is 8" inch diameter . You can make a pretty decent floating ball out of a styrofoam ball (8" inch) , the kind with the smooth surface, not the rough surface sort of styrofoam .
See this web site for styrofoam balls and also large , metallic looking Christmas tree ornaments (6" inches and larger) that are actually light-weight plastic:
Even the more porous , rough surface styrofoam balls can be used if you seal them first with an acrylic spray lacquer , then paint with metallic finish paint, then a final coat of clear acrylic lacquer.
