Product Description:

This enhanced DVD gives detailed explanations of these interesting, yet not so easy to answer, questions:

Here are the questions that provide intrigue for us all and the answers are all explained in the video:

  1. Is it possible to die of a broken heart? - This section explores if the heart can be damaged by emotions. They use a pig heart, as a demonstration because it is the closest animal heart that resembles a human heart. Can the loss of a love break the heart? Maybe so, because there is stress from this experience and that releases adrenalin and excessive adrenalin can kill a person.
  2. Can a person drown in quicksand? Quicksand is a non-Newtonian liquid, which means when it is under pressure it easily gives way. It appears solid, but tiniest amount of pressure on the surface causes it to act more like a liquid than a solid. The good news is watching this video teaches a technique to escape from quicksand.
  3. If hot air rises, why are the tops of mountains so cold? The clue about this answer is air pressure, not temperature.
  4. If nothing escapes from black holes, how do we see them?
  5. If you load up on fast food, will you get fat?
  6. Is it possible to dig through the center of the Earth to reach the other side? This further explores the meaning of pressure using a nitrogen chamber with severe pressure to demonstrate how no human being could pass through the center of the Earth and survive.

This is a great DVD, which is a lot of fun and very enlightening.
