The Brain Teaser: Scroll Down for your Solution
1. Which would you rather have, an old hundred dollar bill or a new one?
2. Picture an empty, clear wine bottle with a cork secured at the top in the usual way. Inside the bottle a metal ring hangs suspended by a string. How is it possible to make the metal ring drop to the bottom of the bottle without touching the ring, the thread, the cork or the bottle?
1. The old bill. It is 99 dollars more than a new ONE (as a 1 dollar bill)
2. By using a magnifying glass and the sun's rays you could burn through the string and consequently cause the ring to drop to the bottom of the bottle.
