I'm wondering if there is an effect where a ball keeps bouncing without anyone touching it. (keeps returning to the same height). If not, what would be a method of accomplishing it?

I suggest you search the science forums, they are coming out with stuff like this all the time. If it does it on it own, then it doesn't have anything to do with the art of magic.

You might be able to achieve something similar to what you want with the mechanism from an automatic putting cup similar to this:

Things are more like they are today than they've ever been before...

Research ways to convert rotary motion to linear motion (this is the opposite of how a locomotive's drive wheels work). Set these mechanics so the linear motion is vertical. Add a perpendicular arm to the linear motion end, which goes to the ball.
Conceal the entire mechanics as you would for an Aga levitation. Manage your angles and you're in business. The device would produce a ball that appears to bounce at a consistent height and speed.

It worked great but I couldn't get the ball to drop back into the mechanism every time so I built a funnel type device to catch the ball. Now the time lapse from the time it enters the machine and shoots the ball back up is to long. It gives away the method. Any idea on how to shorten this time. |

Is there any way you can email me some photos of yours so I can see what you have? Check the one on the left, which shows the rotary to linear motion I am talking about. http://mw.concord.org/modeler/classic.html The illustrations below show my modification to the machine. The mechanism is positioned vertically. The blue is a solid arm, bent at 90 degrees. The red shows the ball fixed to the arm. The audience view would be from the left and the mechanics would be concealed as one would for an Aga.

The answer id quite simple.
Make it from Flubber! ;-) |

Michael,
The Aga idea went right over my head. Neat method. Much better than mine. |

Eldon,
Do you have the means to make something like this? I can think of two applications for my Halloween show. 1) A giant eyeball that jumps up and down from a box or basket. 2) A floating head or skull (slower motion but still cyclical). It could also make for a very cool rising/floating jumbo card. A vertical gooseneck could even allow for a hoop pass.

I came up with a different solution for my forthcoming "Bouncing, Floating Beach Balls" that will soon be published in The Wizards' Journal #29. The beach ball is left bouncing on its own, stage center. Then with a few waves of the mystical magician's hand, it begins the "flubber-like" bouncing, higher and higher until it hits the ceiling and stays there. Just one of many ways to have fun with a beach ball during a magic show.And you thought card on the ceiling was annoying?

Eldon,
Not a problem! My workload is busy, too. I've had to turn down several project requests lately. I am fairly well set for this Halloween anyway (I plan ahead!) Fortunately, there are more Halloweens yet to come, so we've plenty of time to discuss this. ~michael

Awww, gee, guys, now you've me daydreaming. A column of air under the ball, controlled by a solenoid valve, controlled by an Arduino. A few technical things to work out, but that's where the fun is.
