Brain Teaser


Brain Teasers are back with a new series on measuring out liquid volumes! Now put on those thinking caps... - QBF

I. You are handed two water glasses. The smaller glass can hold exactly four ounces of water, the larger exactly nine ounces.

With nothing more than these two glasses and an endless supply of water, your task is to measure exactly six ounces of water.

You can fill or empty either glass as many times as you wish. In the interest of conserving water, try to do this in as few steps as possible.

The Great Way is not difficult for those who have no preferences.
When love and hate are both absent everything becomes clear and undisguised.
Make the smallest distinction however and heaven and earth are set infinitely apart.
