    I still remember being given a model of a simulated combustion engine - one of the best gifts I ever had as a kid. I think this is a great idea.

    @Discofunk: I recall that model, and even understanding the basics of internal combustion, but my parents wouldnt buy me one. They said I should play with dolls. I am SO glad times have changed. (I did manage to get a set of lincoln logs, but only casue my parents thought Lincoln was a good guy.)

    I made a jet engine while I was snowed in one day. Since I was in Japan at the time I happened to have an 8oz aluminum soda bottle lying around (Coffee soda...it's an acquired taste...). For whatever reason I ended up boring a few holes in the sides, pouring some 100 proof whiskey in it, and lighting it on fire. I was momentarily amused watching the flames flickering and lapping around out the vent holes. I left it on an overturned metal pot so it could eventually burn itself out without scorching anything. I went back to browsing the web.


    A few minutes later I notice a weird hissing noise...


    I looked around puzzled, and then I noticed that the occasional orange flames that had been lapping around the aluminum bottle had been replaced by a foot long jet of blue flame shooting out of the bottle. Apparently as the whiskey heated up the fuel air mixture got richer, and the fire started drawing more air in...hence the hissing. And since this bottle of course narrowed towards the top, the exhaust gasses were compressed until the emerged as a rather substantial jet, which burned for a surprisingly long time.


    I've never been able to reproduce the effect so well, but I eventually found that people have been building little camp stoves like this for years our of various tin and alumim cans and such.


    It's a fun little experiment...if you can manage to resist the temptation to chase the doldrums away by simply by drinking the whiskey...

    I'm an engineer. Almost all my friends are engineers. Guess what, nobody is pushing engineering as a career for their kids.


    Better off buying something on human anatomy. Its pretty hard to outsource a doctor and I'm not seeing many of them lose their jobs.

    @shaka999: Just wait until those little tele-robotic operation gizmos become popular. Then all the Indian doctors can skip the part where they come to America and just tele-operate.


    With enough gizmos and gadgets, no job is safe!


    I'm sad now. =(

    I wonder if the gadgets will have the similar accents and be difficult to understand as well?

    On the plus side you can show it off as a modern art masterpiece afterwards.
