- several glasses;
- plastic card;
- thick cardboard;
Bet 1 : Pour some water into a balloon and inflate it. Place a candle in a glass, light it, and cover the glass with the balloon. The candle will go out, and soon the balloon will be drawn into the glass. Now you can pick up the glass using the balloon!
Bet 2: Make a loop with thick paper and a stapler and place it on a narrow glass. Set a coin on top of the loop. Sharply pull the loop out from under the coin – the coin falls right into the glass!
Bet 3: Put a candle behind a glass and light it. Try to blow the candle out through the glass – it actually goes out!
Bet 4: Fill a glass to the brim with water. Place a plastic playing card on the surface of the water so that about half of it is suspended in the air. Balance a coin on the outer edge of the card – it remains steady!
Bet 5: Place a candle in a glass and light it. Thoroughly moisten a napkin with water and cover the glass with it. Press a second glass on top. The candle will go out and the glasses will cling to each other.
Bet 1 : When the glass is covered with the balloon, its oxygen supply is cut off – the candle goes out, the air inside the glass cools down, and the pressure decreases. Atmospheric pressure pushes the balloon into the glass and presses the glass tightly against the balloon.
Bet 2: If you pull out the inner part of the ring, it stretches horizontally and shrinks vertically. In this case, the coin remains unsupported, with only gravity acting on it, and falls vertically downward. If you instead strike the outer part of the ring, it contracts horizontally and sharply increases vertically, instead catapulting the coin into the air.
Bet 3: Choosing the right obstacle is critical for this trick: it must have a streamlined shape like that of a cylindrical glass. When it meets the glass in its path, the air flow is divided and bends around it. The streams of air reunite behind the glass and extinguish the candle.
Bet 4: Surface tension prevents the card from lifting away from the surface of the water – it can even withstand a few coins!
Bet 5: When the glass’s oxygen supply is removed, the candle goes out. The air inside the glasses begins to cool down and the pressure decreases: atmospheric pressure reliably presses the glasses against each other. The napkin allows the pressure between the glasses to equalize, but at the same time seals the glasses by their edges.
