100 Days Project

Nanogirl: Star Science

Nanogirl wants to find 100 friends to do science experiments with her to prove that no matter who you are or what your education level, you can always have fun with science.

Day 33:

How many balloons can we statically stick to Sasha's head?

Today we worked as a team to see how many balloons we could stick to 9 year old Sasha's hair. We managed 12 but could have probably fit more on if we had blown up more balloons.

To start we took some water balloons and blew them <span 1.3;"="">up. We then frantically rubbed the balloon against our heads to build up electrons on the surface of the balloon.  This is static electricity, we call it static because the electricity is not moving and electricity is made from electrons which are part of an atom. 

Electrons have a negative charge and protons which are another part of an atom have a positive charge. We all know that opposites attract so when we took our electron filled balloon and placed it close to Sasha's head, the electrons became attracted to the protons in her hair with enough force that they stuck, we even got one to stick to her eyebrow!
