We were blindfolded while mom drew a dot on our foot. We had to take the pen and draw a dot exactly where mom drew hers.

There are not many receptors on the top of the foot, so look how far away our mark is from moms.

Our fingertips have the most nerve endings and receptors, so we managed to hit the mark exactly where mom had.

Our pen mark was right on top of the one mom made. We use our fingers to feel everything and discover the world around us, so they have so many receptors - we don't use the tops of our feet to feel things, and so they don't have many receptors.
