120v house alternating current converted to direct current, by means of a rectifier, and powering an LED that is rated for 3v. Water conducts electricity! That's why when there is a lightning storm and you are swimming, you want to get out of the water or you could get zapped. This is not a very safe setup that I did here, I knew what I was doing though and no one else was around. Well maybe it is good to have another adult presend incase of shock or something. Just don't be stupid.

  • LED id driven by current not Voltage!!!

    If you over current the LED it will blow!!!

  • lol, Your voice! wtf

  • Fun fact: pure water does not conduct electricity. Mineral content of water, however, does.

    So... Why the water?

  • Cute

  • which is the Volage after the rectifier cause the LED is still working. ?? tnx
