Riddle: In order to figure out what is in a sealed box, you perform some tests. The box seems heavy for its size and is harder to remove from a steel table than when placed on a concrete floor. What kind of object could be inside the box?"
Answer: The answer is magnet because it would be really hard to move a magnet across a steel table since it would attract to the steel-not making it able to move.
Riddle: There are 8 pills. They are all the same size and color. One pill weighs slightly more and is poisonous. You have a balanced scale and you can only use it twice. How can you find the poisonous Pill?
Answer: Take any six pills and divide them into two groups of three each. Weigh putting the 3 pills on each side. If one side weigh's heavier than another, the heavier side consists of the poisonous pill. From the three pill in heavier side, weigh two pills. If one pill is heavier than another, the heavy one is poisonous pill. If both pill weigh same, the remaining third pill is poisonous. If all the 6 pill weigh the same, weigh the remaining two pill and heavy one is poisonous.
