Ball Bearing Box
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
Suppose you have an open topped box that is 5cm x 5cm x 5cm. (capacity: 125 cubic centimetres) Inside the box is a steel ball bearing that is 25 cubic centimetres in size. Next to the box is a two-liter pail filled with mercury. How many cubic centimetres of mercury would you have to pour into the box to completely submerge the ball bearing?

Posted by pusandave on Apr 05, 2002 Yes that is true, but by putting 100 CCs in the box with bearing you can close the lid and completely submerge it. The cube would then be completely full. |

Posted by CCat20 on Oct 06, 2002 If you push it under you run the risk of ending up like Jonny Tremain. |

Posted by boodler on Nov 03, 2005 Surely the ball floats "on" the mercury rather than "in" it! |

Posted by achnid on Dec 31, 2005 um he never said "push it under with your finger" you can use almost any object to push it under. |
