Static Electricity: Salt and Pepper Challenge

We can't get enough static electricity activities around our house.  All the activities we have conducted have proven to be hours of fun!  So today, we are going to use what we have learned about static electricity and experiment with salt and pepper.  I have challenged Jelly Bean and Jumping Bean to try and separate pepper from a mixture of salt and paper. 


This experiment is quite simple.  First, measure out a teaspoon of  salt and pepper.


Next, mix the salt and pepper together.


And now for the challenge!  I asked Jelly Bean and Jumping Bean how they could separate the pepper from the salt.  They thought licking their finger and dipping it into the mixture would work.


Their guess was a good one, but nope, it did not work.


So back to the idea of static electricity.  The girls rubbed the back of a plastic spoon on their fleece jackets and tried to pick up the pepper with the spoon.


And it worked!  Jelly Bean and Jumping Bean were successful in the Salt and Pepper Challenge!
