Hundreds of tricks, stunts, jokes, and puzzles are based on the laws of physics.  
        Here are five problems using household objects that you can try yourself around the dinner table.  
        After you solve them (or look up the answers!), try them on your friends and family.  
        How can elementary science be used to solve them?


1. TRANSPORT THE OLIVE
The object is to transport the olive from the upside-down goblet to the upright goblet without touching anything except the inverted glass.   You're also not allowed to tip the inverted g1ass over or move the olive beyond the surface of the table.
How can this trick be done?

2. DOLLAR BILL BRIDGE
Place the two goblets upright about five inches apart.   Then place a dollar bill apross the two rims like a bridge.   How can you form this bridge so it will support a saltshaker placed on the bridge's center?

3. IMPOSSIBOTTLE
A hard-boiled egg without the shell is shown inside a carafe.   The carafe's neck is too narrow to allow the egg to pass through.   How did it get inside?   And how can you get it out without breaking the carafe or damaging the egg?

4. FLOATING NEEDLE
Will a needle float on water?   Yes, if you know how to go about it.

5. MONETARY BALANCE
The illustration shows a half-dollar held so its edge overlaps the rim of the glass.   How can you cause the coin to stay in this position without the support of your hand or any object that touches the table or the glass?
