C+-+Fire+Safety+Scenario

== __**Fire Safety Scenario! **__ Based on the ideas of Rube Goldberg ===Unlike the previous scenarios, this is a technical problem-solving challenge that will require you to design and/or build your solution. You may work in teams with others or solicit help from an adult. ===

===Before beginning, please go by Mrs. Shaw's room to collect your tea-light candle and sign an agreement regarding its safe and correct use. ===

===Rube Goldberg (1883-1970), a graduate of University of California Berkley in engineering, was a Pulitzer Prize winning cartoonist, sculptor, and author. He became famous for designing hilarious contraptions that perform very simple tasks. Here is an example of one of his cartoons - a machine to kill moths: ===

** Thus, your challenge is to design and/or build a Rube Goldberg Machine that will put out a fire. **

__**Rules:**__ You must... You may... //__You may not__//...
 * Put out (extinguish) the flame of a tealight candle
 * Include at least 4 steps (different actions or mechanisms) in your device.
 * Build the entire device (including the candle) within a 24" x 24" area
 * Build the device using "found" or recyclable objects
 * Extinguish the flame within 1 minute of starting the process in motion.
 * Provide evidence that the machine worked through video, photos, presentation, and/or adult eye-witnesses
 * Include more than 4 steps. (Greater credit is given for greater complexity or more actions/steps.)
 * Begin the process by interacting with the device. For example, you may start the acton by: dropping a marble down a toilet paper tube that hits a row of dominos that falls on thread attached to a needle which then slides down the thread and pops a water balloon that puts out the flame.
 * Restart the process if it does not work as planned. (You will have 3 opportunities to prove your device works.)
 * Research simple machines, Rube Goldberg, and other helpful sites.
 * Ask adults for outside help
 * Interact with the machine in any way except to start the process in motion. Once the action begins, you may not interrupt the flow, except as a safety precaution.
 * Remove the tealight from its protective, metal case
 * Use animals (experimentally or otherwise) as a part of the device
 * Use explosive, excesively sharp, illegal, incendiary, and/or other dangerous, harmful, and inappropriate materials, nor may you use approved materials inappropriately
 * Purchase (spend significant money) on any part of the device
 * Cause the flame to spread or in any way harm persons, animals, or materials
 * Plagiarize or steal ideas, concepts, designs, photos, videos, etc. from others
