I read somewhere that a good rubber ball will bounce back two thirds of the drop height. The original plan was to go to the top of a tall building, drop the ball then run down stairs to two thirds of the height to see if you could catch the ball on the way back
BUT now all I want to do is to get
one of those massive rubber band balls (as made famous by competing farmers somewhere in US), hang it from the bottom of a hot air balloon (a big one, or a chinook) take it a mile high, and cut the rope. I had envisaged doing it over an old airfield.
Oh, and film it for repeat viewings.

Better yet to make a carefully timed bungee leap, so that the bottom of the leap coincides with the top of the bounce. |

And bring a paper bag, to carry your teeth home afterwards ..... |

Ripley's Believe it or Not did just that (they used a plane, rather than a balloon or helicopter). The ball exploded on impact. When they found the crater some minutes later, many of the chunks of rubber band were still vibrating. |

How do you add rubber bands to a ball that's already two feet in diameter? Do you make a rubber band chain and wrap it around and then tie a knot? |
|
| |
anything involving rubber bands gets (+). The more the better. Even better to have thousands in a ball. |

They use giant rubber bands. They're used for holding large
items together in shipping. |

You can only drop it from so high before the law of diminishing returns takes effect. (aside - who the hell passed that law? Let us all join in the effort to repeal it!) |
|
| |
The ball reaches terminal velocity after it has been falling a while and then any higher does not make it bounce any further higher. |
|
| |
Or you drop it in vaccuum. |
|
| |
How long's that then? About the time it takes to drink a cup of tea? |
|
| |
Snoyes has exactly the same story as in the link, i think. |
|
| |
Yeah, it's baked. Wish I'd seen it. If they had done it from a balloon they could have taken it up a little bit, dropped it and repeated higher and higher until disintegration. |
