Why does the spoon look bent What is the illusion called?
It is an optical illusion, called refraction. Light only bends when it passes from a substance of one density into a substance of a different density—in this case from air to water. Next, trying seeing how the concave (turning inwards) surface of a spoon reflects the image upside down.
How much water does David Blaine drink?
A webcam was installed inside the case so that viewers could observe his progress. The stunt lasted 44 days, during which Blaine drank 1.2 US gallons (4.5 litres) of water per day and did not eat.
Why do pencils look bent in water?
In this experiment, light first travels through the air – which is easy to move through – and then through the water, where it slows down. This change in speed causes the light to bend, or refract, meaning that the part of the pencil that is in the water will appear shifted.
Did David Blaine spend 7 days underwater?
Blaine has gained world-wide fame by creating marathon, death-defying stunts. In 1999, he buried himself alive in a see-through coffin for seven days. A year later, he was frozen in a block of ice for 63 hours.

How did Copperfield fly?
During the trick, Copperfield flies acrobatically on the stage, performs a backflip in midair, and then has spinning hoops passed around him, supposedly to prove that he is not suspended by wires. The illusion sometimes ends with a falcon named Icarus grasping Copperfield by the wrist and flying off stage with him.
Can you actually levitate?
Normal things, even humans, can levitate if they are placed in a strong magnetic field. Such materials can be levitated using magnetic fields of about 10 Tesla.
Why does light refract in glass?
Light waves change speed when they pass across the boundary between two substances with a different density , such as air and glass. This causes them to change direction, an effect called refraction . the light speeds up going into a less dense substance, and the ray bends away from the normal.
Why do things look bigger in water?
The surface of a water drop curves outward to make a dome. This outward, or convex, curvature bends light rays inward. The surface of a smaller drop is even more curved, creating a bigger change in direction of the light ray. The result is a larger magnification.
How did David Blaine spend 7 days underwater?
In 1999, he buried himself alive in a see-through coffin for seven days. A year later, he was frozen in a block of ice for 63 hours. And, in 2002, he perched himself 90 feet above the ground for 36 hours. He has trained harder for this underwater exploit than for any of those previous endeavors.
What is bending spoon?
