Instead of just the usual spring, the barrel also incorporates a small combustion chamber and a piston connected to the foot of the stick.
At the appropriate point diesel is injected and is compressed by the upstroke, ignites and the explosion forces the piston down again, propelling stick and rider in to the air.
Hopefully the fuel and batteries for the glow plugs could be incorporated into the stick.-- rambling_sid, Dec 16 2004 Combustible Gas Powered Pogo Stick http://www.bpmlegal.com/wpogo.html [skinflaps, Dec 16 2004] Similar http://news.bbc.co....sci/tech/820398.stm [paraffin power, Dec 17 2004] Video of this thing in actual use. https://www.youtube...watch?v=iyM0rkoO-XIStart at 2:10, the dangerous, almost immediately banned gas powered pogo stick. [doctorremulac3, Sep 19 2022] Baked, not with diesel though. However the same principle.-- skinflaps, Dec 16 2004 [skinflaps], the fascinated terror expressed on your link is hilarious.

I have always thought diesel power the best for a simple powered pogo stick. Add computer control to limit or shut off power when the rider is off balance and youv'e got something.-- Pat-O-Cake, Jan 19 2008 Just got a vote from me.
I had the same idea, but was playing with a name begining with 'B' for briiliant or some other word, and then carrying on with 'Internal Combustion Engine Pogo Stick' I.e. BICEPS-- Ling, Nov 28 2010 I thought this would be a great idea, then checked the HB archives. Yup. Somebody else not only thought of it first, it was actually manufactured and sold at one point.-- doctorremulac3, Nov 29 2010 //The problems are solvable with modern technology// sp. "medicine".-- FlyingToaster, Nov 30 2010 You could make it fire blank pistol cartridges for the thrust, which would be cool, however the main advantage is that it could be then magazine fed.-- Custardguts, Nov 30 2010 random, halfbakery
