Benny wonders why when he presses his finger against a map nothing happens to the map. However, if he presses a thumbtack into the map using
the same force, the tack will probably poke a hole in the map. This is what his friends said was the reason:
Heather: I think it’s because the tack is made of metal.
Steve: I think it’s because your finger has more surface area.
Ashia: I think it’s because your finger is warm.
With whom do you agree most?
