Well, not really. Visiting a near by park in Perkasie Pa as a kid I always wondered about this paved circle. Not until recently did I discover that it was a 67 foot dia. tether circle track. It hasn't been used in years and appears to have only two spots needing repair. A spot of weeding would do it...

BOOM! needle in eye

Gives me the willies just thinking about it

Ya know Larry, you just gave me a good idea. I could use the extra pressure to drive a piston to pump air in to my tiny pules rocket to mix with the hydrogen. Using two syringes and a block of plastic with a chemical reaction chamber and passages whittled out of it. One passages for the release of h...

Here's a crude way I thought of in making hydrogen on a small scale. I'm using powdered aluminum and hydrochloric acid. H gas is collected in the syringe and is released through the needle. At first it seems to backfire, but it actually pops due to a build up of pressure from make'n H. Plenty of roo...

Wow, look at those babies...Price is right too. Thanks for posting all these goodies from ebey.

Here's a picture of what's going on inside. They're barely discernable in the stills.

Here's a shot just after the glass started to flick splinters. The only thing I had on hand for glass was an old smith water temp guage. So,...no more gauge.

Thak's guys here are a few stills. You can just see the pulse inside.

Here's a look in side this little creature running. http://www.youtube.com/watch?v=8Mn8Q-bfaxQ

Next goal--make the little bugger run on fuel and atmospheric air
