2. What is a
Plasma Ball?
A Plasma Ball is a clear glass sphere filled with noble
gases with a high-voltage electrode in the centre of
the sphere.
The most common noble gas used is Neon.
Neon is a chemical element with symbol Ne and
atomic number 10.
4. What happens
when you touch it?
Placing a hand near the glass
offers an attractive place for
the energy to flow.
Touching it causes a single
filament, from the inner ball to
the point of contact, to
become brighter and thinner.
The filament is brighter
because there is more current
flowing through it.
