Instead of simple balls, Newton's Russian Roulette Cradle
features live munitions hanging nose to tail. An amplitude
calibration gauge enables the initial priming motion to be
repeated and gradually increased until the inevitable
catastrophic outcome is achieved.
This is a particularly dangerous
device, and I do not
recommend constructing it, or tempting destiny by
competitively engaging with its operation.

<Wonders if this idea can be modified into Newton's Russian Roulette Cat's Cradle> |

In your case, 40mm grenade shells would be a good choice of munition. (The neighbourhood cats will come in through the gaping holes and eat the left-overs) |

Actually, a Newton's cradle "Godiva device", using fissile material in the spheres, would be amusing; every time the five balls came into momentary contact, there would be a flash of Cherenkov radiation ... |

I also wrote up this variation:
Newton's
Inverted Cradle |
|
| |
Newton's Inverted Cradle is for those who have
grown tired of the regular version of the famous
desktop toy. (or any of the other ones here on the
HB) In this version, a heavy metal plate is fixed
above the hanging balls which are now tethered at
the base, and hang below the metal plate because
they are composed of neodymium magnets, that
are strongly attracted to each other as well as the
metal plate above them. |
|
| |
Pulling out of alignment and releasing the end ball
causes it spring upwards in an arc, and transfer its
energy to the line of hanging balls, forcing the end
one to carry out a reciprocal action. |

I suspect you'll have problems with that one, [xen]. Gravity is
constant throughout the swing of a regular Newton's Cradle; in
contrast, the magnetic force on yours will be much, much
greater at the top of their arc. I suspect this will lead to
rapid damping. |

That's why I didn't post it..... Just thought it might
jitter and not do much else, but with some timed
on and off electromagnets in the system as well, it
could be made to work differently. Maybe.... |

Yes. Or you could implement it as a computer animation. |
