danger being so close to the
clouds and all?

Answer: They form a Faraday
Cage i.e., they are surrounded
by metal; if you are
surrounded by metal you are                     +   + +
safe the electricity flows                  +             +
around the outside


                                 Safest place during a lightning
                                 storm is in a plane or car
                                                             5
                                 because it is a Faraday Cage

Lightning
Jacob’s Ladder
Corona
Tesla Sparks
                            are all related.

Principle:   Air becomes ionized, and
             therefore conducts electricity.
             Lot’s of it, so the current heats up the air,
             excites the atoms/molecules which emit light.

SAFETY FIRST!
   Distance at least 20 ft.
   Computers, Gameboys, CD players,
    telephones to the back of the room –
    unplugged, switched off!
   Hearing aids off, pacemakers out of         1 Million
    room                                         Volts!
                                                DANGER
       Normally you can't see, hear or smell
        electricity, but the Tesla Coil makes
         • Bright sparks
         • Loud crackling noise
         • The air smell bad (Ozone)
                                         BRACE YOURSELF!
