Move your mouse and don't let the bell fall!! P.S - You can use the random number generator and put in "175 to 185" for a little randomness,and,you might have guessed,but if you remove 5 from 175( 170) you'll add 5 to 185(190) so the average isnt below or above 180 sorry if this sounds like crazy speak just see inside(that blue button) and check out the code!
