Exidor's Logic Puzzle Place 
Welcome to Exidor's Logic Puzzle Place. As you all know I am from planet Ork. My mission is to find out how intelligent the human brain is. Therefore I have made some tests. You people think of it as fun, but in reality it is a experiment to test the limits of the human brain. So have fun with these puzzles and if you have solved them click on 'next site' at the bottom of the page. There are some Venusians, Kryptonians and other alliances (read aliens) who also want to test you.Good luck.
Puzzle 1
Burning ropeThere are two lengths of rope.
Each one can burn in exactly one hour.
They are not necessarily of the same length or width as each other.
They also are not of uniform width (may be wider in middle than on the end), thus burning half of the rope is not necessarily 1/2 hour.
By burning the ropes, how do you measure exactly 45 minutes worth of time?
Puzzle 2
A quick test of intelligenceDon't cheat! Because if you did, the test would be no fun.I promise, there are no tricks to the test.
