There are 8 marbles that weigh 1 ounce each, and 1 marble that weighs 1.1 ounces. The marbles are all uniform in size, appearance, and shape. You have a balance that contains 2 trays. You are only able to use the scale 2 times. How do you determine which marble is the heaviest using only the scale and marbles in 2 weighings

You have 9 marbles total. Divide them into three groups of three.

Weigh group 1 and group 2 against each other, if one is heavier than the other, then you know that it contains the heavy marble, if they are of equal weight, then you know the heavy marble lies in the third group.

Take the heavy group and weigh any two marbles against each other. If one is heavier, than that is your marble. If they are the same weight, then the heavy one is the remaining marble in that group.

Here's another classic for you:

I never was, am always to be,
No one ever saw me, nor ever will
And yet I am the confidence of all
To live and breathe on this terrestrial ball.
