(Credit: Jeff Fitlow/Rice University)Located on a 300-acre forested campus in Houston, Rice University is consistently ranked among the nation’s top 20 universities by U.S. News & World Report. Rice has highly respected schools of Architecture, Business, Continuing Studies, Engineering, Humanities, Music, Natural Sciences and Social Sciences and is home to the Baker Institute for Public Policy. With 3,910 undergraduates and 2,809 graduate students, Rice’s undergraduate student-to-faculty ratio is 6-to-1. Its residential college system builds close-knit communities and lifelong friendships, just one reason why Rice is ranked No. 1 for happiest students and for lots of race/class interaction by the Princeton Review. Rice is also rated as a best value among private universities by Kiplinger’s Personal Finance.

The launcher was built at Rice’s Oshman Engineering Design Kitchen.

What makes the light go on? It’s not magic. It’s electromagnetism,” said Rachel Nguyen, a sophomore in electrical and computer engineering (ECE) at Rice and a member of the design team that built a device for the museum’s “Shocks and Jolts” exhibit.Assembled in Rice’s Oshman Engineering Design Kitchen, the exhibit was installed in the museum in May. The museum calls the Rice creation the Electromagnetic Launcher. The interactive device is simple in design: Two transparent plastic tubes are angled at 45 degrees on a laser-cut wooden frame. In each tube are three coils of copper wire connected to a power source, with small lightbulbs in place at the top of the tubes.By pushing the first of three buttons, each corresponding to one of the coils, a museum visitor electrifies the first coil and releases the magnetized projectile up the tube. As the projectile reaches the second coil, the object is to press the second button and electrify the coil, which in effect becomes a solenoid and sends the object further up the tube. The same follows with the third button and coil. If the museum visitor times the button-pressing successfully, the projectile will reach the top and turn on the light, and the visitor wins the game.“The coils become temporary magnets. The direction of the coils determines the poles of the magnet,” said Nguyen, who grew up in Houston and visited the Children’s Museum as a child.“The biggest thing we wanted to get across was the relationship between electricity and magnetism, but doing it in a fun way,” said Saad Yousaf, a sophomore in mechanical engineering. All team members are sophomores who met their freshman year in the Introduction to Engineering Design class taught by Rice lecturer Matthew Wettergreen. The other team members are Sammi Lu and Karen Vasquez, both in bioengineering.Keith Ostfeld, the museum’s director of digital learning, explained how the Electromagnetic Launcher complements the rest of the “Shocks and Jolts” exhibit.“We discovered kids typically aren’t introduced to electricity in school until the fourth or fifth grade, and then they don’t study it again until high school,” Ostfeld said. “It’s a real shame because kids live in a world of electricity and electronics and are fascinated by it. So we created a space where families and kids of any age can immerse themselves in electrical explorations.”The museum attracts 800,000 visitors each year. The team sponsors are Rice alumna Carolyn Huff and Harrell Huff, and the students’ faculty adviser is Gene Frantz, professor in the practice of signal processing in ECE.-30-Follow Rice News and Media Relations via Twitter @RiceUNewsVideo: to the Children’s Museum of Houston test the Electromagnetic Launcher, an interactive exhibit that demonstrates the principles of electromagnetism.
