Exploding Toilet, Ice Bullet, Who Gets Wetter (in the rain)?

This episode is part of Collection 1, disc 1, episode 1. It is ALSO the first episode of Season 2.

Myths tested:
Can a person be propelled off a toilet seat by dropping a lit cigarette into a toilet bowl when filled with various combustible materials?
Is running better than walking to keep dry in the rain?
Is it possible to make a "magic bullet" out of ice?

The Science behind Ice Bullet
The main ideas here involve materials, the physics of how bullets are fired, and the amazing strength of human skin. The key questions:
• How does a gun fire a bullet? How hot does it get inside a gun?
• How strong is water ice? Can a usable bullet be made of frozen water, meat or gelatin?
• What does it take to penetrate human skin with a projectile?
Students can explore the properties of frozen water/meat/gelatin, how guns work, and human skin analogs. (This myth is revisited in Episode 14.)

The Science behind Umbrella Gun
The disguising of firearms and poisoning of bullets are the main ideas here. The key questions:
• Is it possible to disguise a gun as an umbrella?
• How can a bullet carry poison?
• Is it possible to kill someone using such a weapon?
Students can explore spy technologies, hidden weapons, poisons, and the history of the Cold War.

The Science behind Outrunning the Rain
The speed of falling rain and measuring accurately are the main ideas here. The key questions:
• Is it possible to outrun raindrops?
• How fast does rain fall?
• How fast can a human run?
Students can explore the speed of falling drops of water, and how fast humans can run. (This myth is revisited in Episode 38.)

The Science behind Gasoline Toilet
The flammability/combustion of gasoline and the strength of porcelain are the main ideas here. The key questions:
• Under what conditions is gasoline flammable/combustible?
• What does it take to make a toilet explode?
Students can explore the fire triangle (fuel/air/heat), and the durability of porcelain fixtures.

Biscuit Bazooka, Vacuum Toilet, Leaping Lawyer

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).
