Everyone likes hula hoops. Everyone likes railguns. Ergo: combine the two to create a self-propelled hula hoop.
By embedding magnetic accelerators within a circular tube of plastic which contains a ball bearing. Careful timing of the electromagnets will accelerate the ball bearing clockwise causing
the hoop itself to spin counterclockwise. The motive power would have to come from thin battery-packs spread equidistantly around the hoop.
Now, with minimal hip rotation, you can hula-hoop for hours at hitherto unachievable speeds.

Excellent! It should also be possible, if the ball
bearing is magnetized, to recharge the batteries by
active hula hooping. |

But, but, [Max] that would mean working harder than with a normal hula hoop. Perhaps a battery pack on the hip could recharge the hoop mounted batteries via induction. |
|
| |
[bigsleep], the saving grace about an uncontrollably weaponized version is that being in the center of the hoop would be the safest place to be. |

You'd be a death-dealing one man commando squad - until you lost your bearings of course. |

This is a coil gun, not a rail gun, shirley? |

I keep reading this as "Religion Hula Hoop", and that
would be cool, and probably start a real flamewar. |
|
| |
it's called a gauss gun, though I suppose coil gun also portrays the idea |
|
| |
a railgun uses the inductive force created by the sudden change in electric field (created by simply turning the circuit on) to accelerate the projectile, which is part of the circuit |
