They say opposites attract and
that couldn't be truer with these fun static electricity experiments.
Find out about positively and negatively charged particles using a few
basic items, can you control if they will be attracted or unattracted to
each other?

What's happening?
Rubbing the balloons
against the woolen fabric or your hair creates static electricity. This
involves negatively charged particles (electrons) jumping to positively
charged objects. When you rub the balloons against your hair or the
fabric they become negatively charged, they have taken some of the
electrons from the hair/fabric and left them positively charged.
They say opposites
attract and that is certainly the case in these experiments, your
positively charged hair is attracted to the negatively charged balloon
and starts to rise up to meet it. This is similar to the aluminium can
which is drawn to the negatively charged balloon as the area near it
becomes positively charged, once again opposites attract.
In the first
experiment both the balloons were negatively charged after rubbing them
against the woolen fabric, because of this they were unattracted to each
other.
