Last year one of my students found a pogo stick and used it to
periodically hop around all over the studio. Annoying as this was,
it
would have been ten times worse had it been of the Loaded Pogo
Stick
variety.
This variation on the conventional pogo stick incorporates a holder
for
a
roll of percussion caps, similar to those inserted into toy six-gun
shooters.
With the now primed, Loaded Pogo-stick each bounce is
accompanied
by a loud bang, a shower of sparks, and a small puff of smoke,
creating
the illusion that the jumper is being propelled along, instead of
just
jumping up and down.

+ cute idea. (water for summer?) pogo fountain! |
|
| |
somebody make a mobile phone(handy) charger using a
pogo. |
|
| |
I'm thinking of re-naming it, but too busy to devote any time to matter tonight. |

//creating the illusion that the jumper is being propelled along//
Illusion ? for shame. |

I like the shotgun cartridge scheme. One could use blanks, for safety. The kick of a shotgun is just about perfect for this. The jumper could wear a large bandolier. |
|
| |
Two crossed bandoliers, which are belt fed into the pogo stick. The unfortunate constriction of the bandoliers about the wearer would help enforce configuration discipline. |
|
| |
This could be done by using a Mossberg pump-action 12-guage shotgun as the "stick". With the 8 round magazine, filled with black powder blanks, and a strong spring, quite useful altitudes are attainable. |
|
| |
Given the 2.7 cm^2 area of the barrel, and the breech pressure of around 500kg/cm^2 (for BP) the instantaneous upforce should be able to propel an average 70Kg adult some distance into the air. The impact with the ground on descent would re-cock the weapon and trigger firing. |

The principle is exactly analogous to a semi-automatic captive bolt humane killer. And would most likely have a similar effect on the user. It is an extremely dangerous inadvisable use of an illegally modified firearm. [+]. |
