whoa check it out…that is CRAZY!

Have you ever heard of such a cool DIY project?  Apparently this ambitious home inventor shows us how to make an actual rocket engine from home.  Needless to say do not attempt without the supervision of a professional.  Here is more about the video from the inventor:

I built a small rocket engine for demonstration purposes. The engine is built from a 2″ diameter acrylic rod through which I drilled a 0.5″ hole. The oxygen at 80 psi or less is passed through the hole and then is forced through a convergent-divergent nozzle at the tail end. The nozzle’s throat is about 0.25″ and expands to 0.625″. I lit the engine by inserting a burning cotton swab (with wooden stick) while a small amount of oxygen was flowing. The acrylic catches fire very easily in a pure oxygen environment. The engine can be throttled and shut off completely, which is a major benefit to hybrid engine designs. Solid-fuel rockets cannot be throttled or shut off, which makes them difficult to control.

Have you seen anything like this before?  And could this be constructed in other coworking facilities and garages and if so what are the applications?

Although dangerous, we are glad this home experimenter video recorded this and uploaded it.  Not many people have made something like this.

Let’s watch this rocket engine in the video on page 2
