Mimimum hight needed to...

Prof_Sai · 08-28-2007

I just did a quick calculation and determined that 29 inches (2 ft 5 in) seems to be the minimum size needed to turn a door knob. (Your hands would just be able to grasp the knob enough to turn it.)

For a story about a slow shrink, these kinds of landmarks would be very important. Lets come up with the minimum heights for various other activities. How big do you need to be to drive an ordinary car? Order at a restaurant? Shop at a grocery store?
