I wanted to see how accurate the measurements were using two different tools to measure with. Sometimes I have this thought that the stiff ruler might be not as accurate because the tape measure can bend to the curve of the thing being measured. Or maybe the ruler is better because it's call it like you see it. So I compare the two, by measuring the tops of My toes. The results were fun, and pretty similar. There were differences though. I love science! hehe.
