Video: High School Students 'TP' JPL For Science

The 15th annual JPL Invention Challenge involved catapults and toilet paper. Schools invited included Arcadia, Crescenta Valley, Diamond Bar, Temple City and South Pasadena.

It's not every day you see toilet paper airborne on the courtyard of the Jet Propulsion Laboratory's impeccably manicured La Cañada Flintridge campus.

JPL's 15th annual Invention Challenge charged teams of students from 18 California high schools with designing a catapult capable of propelling a roll of toilet paper into the air. The team whose device creates the longest unbroken stream of tissue paper wins.

The catapults had to stay within certain perameters. They had to: 

  • Be set off by a single trigger, such as a cut of string or a switch.
  • Use safe energy sources.
  • Be no taller than 8 feet, and no wider than 6.5 feet.
  • Be made from non-toxic, safe materials.

Monroe Magnet High School took first place with a 35-foot, 5-inch stream of toilet paper; Village Christian took second place with a 33-foot, 11-inch stream; South Pasadena High School took third with a 32-foot, 1-inch stream.

Other San Gabriel Valley high schools that competed included Arcadia, Crescenta Valley, Diamond Bar, Temple City and South Pasadena.

The student teams were invited to the JPL Invention Challenge based on results from two regional contests held last month.

Hi Susan, The graphic shows that in only one year from 2002-2011 were more Hispanics arrested thanRead More Blacks (2011) - if you hover your mouse over each point you can see the raw number of arrests for each group each year. That's despite there being a substantially larger Hispanic population in L.A. County. The data comes from the Dept. of Justice and was reported by the ACLU - and I believe the point of the report is that there is racial profiling going on, not to suggest that black people are using more pot. In fact, the study suggests that there is not significantly more prevalent pot use among any one racial group. The figure 2.6 times as likely refers to blacks vs. whites, as in mentioned in the first sentence of the article, and comes from the ACLU study. Our intention was definitely not sensationalism but rather to direct readers to this national ACLU study that included L.A. County data. Let me know if I can answer any other questions.
