Bend the coat hanger so it makes a stand. Bend the top part out flat as shown in the picture.
Tie one Cheerio to each end of the thread, and wrap the thread around the end of the coat hanger at the top. Make sure the Cheerios are even and are not touching the table.
Now, rub the comb through the piece of wool, touch the comb to one of the Cheerios and see what happens! Try rubbing other materials like cotton, silk, a balloon, or even combing your hair to make a charge.
