Once you have marked a ruler up the same, you can measure someone else's
reaction time like this..

                 ΪΔΏ Tester hold
                 ³ ³ top & releases
                 ³ ³ when testee
      Testee has ³ ³ least suspects.
       finger &  ³ ³
     thumb ready ³ ³
       to grab   ³v³
        bottom   ΐΔΩ

Ideally the testee should not be able to see the tester, so there are no clues
when the release is to take place.

Anything below 120mS is usually considered cheating in sports.
Anything over 250mS & you are dead.

It assumes G = 9.81N/m/m, e.g. you are on the Earth.

N.B. YOU CAN'T TEST YOURSELF!


Why Don't U send an interesting bul?
