This episode is part of Collection 3, disc 1, episode 2. It is ALSO the second episode of Season 1.
Myths tested:
Can an airplane toilet create enough suction to cause a person to become stuck on it?
Can a can of biscuit dough explode in a hot car?
Can a person throw himself through a skyscraper window?
The Science behind Stuck on an Airplane ToiletSuction/vaccuum, seals and air pressure are the main ideas here. The key questions:
• How much suction is generated by an airplane toilet flush?
• Can a human butt seal the opening of an airplane toilet seat?
• How much suction can human flesh take without damage?
Students can explore the relationship between suction and air pressure, and the amazing tensile strength of human flesh.
The Science behind Exploding Biscuit Dough The chemistry of canned biscuits and the hardness of the human skull are the main ideas here. The key questions:
• What is the chemistry of canned self-rising biscuits?
• How much pressure is generated by a can of self-rising biscuits rupturing?
• How much heat is required to rupture a can of self-rising biscuits?
• What is required to rupture someone's skull?
Students can explore the chemistry of canned and self-rising foods, and the amazing hardness of the human skull.
The Science behind Leaping Lawyer
The hardness of skyscraper glass, the speed of the runner, and the speed of a bullet are the main ideas here. The key questions:
• What is the speed of the runner? is it sufficient to break skyscraper window glass?
• How fast does a bullet travel? is it sufficient to break skyscraper window glass?
• What is required to build a rig to test this myth?
Students can explore the different qualities of different kinds of window glass, the different speeds of different bullets shot from different guns, and terminal velocity (how fast someone would fall from a window).
