The MythBusters dive into six water-related myths, finding out how far bullets can penetrate water, whether hitting the surface is really the same as hitting concrete and if walking on water is possible using ninja technology.

The MythBusters investigate six myths about pressure. They build a pressure cannon to see if a ping pong ball impact could be fatal. They also test the affect of water pressure on a deep sea diver, find out if firehose pressure is enough to lift a car; if a bullet can be fired in space; if a vacuum cleaner can lift a car; and if steam followed by rain can cause a railroad tanker car to implode.

The team test if people can be electrocuted by lightning while talking on the phone, if a stun gun could use water instead of wires, and if peeing on the electrified rail of a subway line could give a fatal shock.

The team find out if a skydiver can streamline their body like Keanu in Point Break, if a penny dropped from the Empire State Building could kill a person, and if it was paint and not hydrogen that caused the Hindenburg disaster.
