Alkire's project was probably the most complicated and highly technical of the bunch, although his findings were equally dubious due to the subject content: Do man-made light sources harm you?
"My biggest finding," he said, "is that LCD displays, such as cell phones and computer screens, may produce very low levels of radiation."
LCD stands for liquid crystal display, Alkire said, adding that he built a cloud chamber using rubbing alcohol and dry ice. He then sealed a glass fish tank and placed a heater on top to create "a super saturated environment."
Alkire said he came up with the idea after taking a trip to Griffith Observatory in Los Angeles and seeing the cloud chamber there. His father, Michael Alkire, an anesthesiologist, lent a hand.
"I love lighting, special effects and theatrical," the younger Alkire said. "And I'm around it a lot. So I want to make sure I'm safe and that the industry is safe."
He said he was thinking about becoming a physicist for a career.
Fukushima garnered second place in the microbiology division by studying at what point bacteria starts growing on lemons.
To find out, he went around to 36 different restaurants in Orange County, from McDonald's to Burger King to Jack in the Box, and asked them for slices of lemons, if they'd be so kind.
"I came up with the idea after seeing how much my mom would always ask for lemons in her iced tea, and it got me to thinking if they were dangerous or not," he said.
His conclusion is that after the third day, without fail, bacteria begins to grow, and it would be prudent to squeeze the lemon juice out of the lemon instead of dunking the whole lemon in the drink.
