Hello my name is Iris and I'm a host at the Ontario Science Centre and today I'm going
to be showing you the plasma ball.
This is our plasma ball and we know that plasma is the 4th state of matter. You may be familiar
with solids, liquids and gasses and those are other states of matter.
The state of matter is generally determined by the level of energy in some material so
plasma is a very high state of energy.
Inside this ball we have a number of inert gasses. And when the gasses become energized
they light up and turn into plasma.
So if I put my hand on the ball I give it a very good method to escape. And to prove
to you that there is energy or electricity-flowing electrons going through my body-I have this
light stick.
So if I can get Koby to hang on to the other end of the light stick-you see right there
he's providing a path for the electricity to escape-and as you can see it causes the
light tube to light up.
