Doctor Oz was joined by Bill Nye the Science Guy, host of Stuff Happens with Bill Nye, in a segment called Extreme Myths Busted. Some of the most extreme myths were discussed: like is it safe to stand in front of a microwave while it is on, can a human voice or opera singer break glass and will high voltage electricity kill you?
Myth #1: It Is Dangerous to Stand in Front of the Microwave
BUSTED! It is not dangerous to stand in front of the microwave. The years of hearing my mother tell me not to stand in front of the microwave because it emits dangerous radiation was all for naught! Dr Oz and Billy Nye stood in front of the microwave with pieces of aluminum foil and put another piece of aluminum foil inside the microwave. There were lots of lightening and sparks from the aluminum in the microwave, but no sparks on the pieces of aluminum foil they held outside of the oven. The reason the microwave radiation does not come through is because the glass door on microwaves has a screen that absorbs the micro waves. The waves hit the metal screen and get pulled down around the frame of the oven. And the microwave turns off at the speed of light when you open the door, so you aren’t exposed.
Myth #2: Human Voice Can Shatter Glass
Confirmed!!! As a child, we all noticed that if we wet our finger and dragged it around the rim of a glass, it made a sound that would annoy everyone around us. That humming sound is caused by a vibration at the natural frequency of the glass. Jaimie, a singer, sang a note that was the exact same natural frequency as the glass, and sure enough, the glass shattered. It is hard to do because you have to sing the note loud enough, around 117 decibels in order to shatter the glass – but Doctor Oz was able to shatter the glass too, with the help of a microphone.
Myth #3: High Voltage Electricity Will Kill You
BUSTED!!! Bill Nye took a pickle and put 2 electrodes in it attached to a variable transformer, and put a large amount of electricity into the pickle. There was some yellow, smoke and sizzling on the pickle when set to 110 volts, but this was mainly due to the high current of 10 amps of electricity in conjunction with the sodium and vinegar in the pickle. Next, Dr Oz put a few foil pie pans on a volunteers head and had her touch a metal ball with 500,000 volts of electricity. The aluminum pie pans went flying off of her head and her hair did stand up, but she was fine. Bill Nye said she was a particularly good volunteer because she has shoulder length blonde hair.
