In this science experiment we will explore static electricity and make small styrofoam balls stick to
the sides of a plastic tube magically
. In the process will learn how opposite charges attract
(negative electrons and positive protons) and transferring electrons from one s
urface to another.
It's called a static tube.


Materials For Static Tube:






  • Static Tube with styrofoam balls
  • Wool Cloth or Hand










Watch The StaticTube Video:



























Process for Static
Tube:

1) Get your wool cloth out or use your hand.

2) Rub it fast and vigorously on the outside of the plastic static tube with the styrofoam balls inside
for about 15 seconds.

3) Stop! Watch the as the styrofoam balls jump, dance and then stick to the walls of the plastic tube.


The Science Behind Static Tube.  

In this science experiment we transferring electrons from the wool cloth (or hand) to the surface of
the p
lastic tube. Rubbing the plastic tube with the wool cloth completes the transfer of electrons to
it's surface
. The electrons now on the surface of the tube are attracted to the protons in the
s
tyrofoam balls.  

Opposites attract each other. In this case we have electrons which have a negative charge (o
n the
surface of the plastic tube
) and protons that have a positive charge (styrofoam balls). When they
get close to each other the attraction makes them
, jump, dance, then stick to the plastic tubes
walls
.  

More specifically, the negatively charged electrons on the surface of the plastic tube repel the
negatively charged electrons inside the styrofoam balls. Since the negative electrons in the
styrofoam is being pushed away (repelled), the positive charges in the styrofoam balls are closer  
to the plastic tubes walls. When the positive charges (styrofoam balls) and negative charges (wall
of plastic tube) get close they attract and stick to each other.
