in my corn pops, i acquired a spongebob squarepants pencil topper with big poofy hair. the green hair is supposed to change color when you warm it up with your hands, or your breath.
i blew on it a while. i rubbed it with my hands. nothing.
then, i remembered that i lived in texas, in august. i put the pencil topper in the freezer for a while.
it came out with blue hair. i rubbed it and blew on it and succeeded in making green hair.
the directions say that the hair is supposed to change color when you heat it up. around here, that means you have to cool it down.
