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

ÚÄ¿ 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 ÀÄÙ

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?
