What Is Glow
Jewelry
A
lightstick,
also called a
glowstick, is a
transparent
plastic tube
which
contains
chemical
fluids
held apart
in two
compartments.
The outer
plastic
tube
contains
one part
of the
chemical
mixture,
and the
inner
compartment
is a glass
or brittle
plastic
tube
containing
the second
mixture.
If the
lightstick
is bent,
the inner
tube
breaks and
the
chemicals
mix,
resulting
in a
reaction
that emits
light but
not
necessarily
heat. This
phenomenon
is called
chemoluminescence.
