Ask a kid up from the audience to help with your next effect. But, before he can help, you've got to make sure that he's tall enough. You ask him how tall he is. If he's like most kids, he won't know the answer. Well, what the heck, ask him to take a guess. You guess that he's about six feet tall. (Since the kid is only 3 foot nothing, this will get a good laugh!) So, you bring out your ruler to measure the kid. This is a really big ruler of the unfolding variety. You unfold the ruler, and sure enough, the kid is Six Feet Tall! You see, the ruler is made up of Six Big Feet! It's a great gag for your kid shows. Made of high quality Bristol board, beautifully silk screened.
