We asked 18-year-old Iris Ahronowitz, the Harvard-bound whiz who captained North Hollywood High School's science bowl team to a No. 2 national ranking for the second consecutive year, to weigh in on what's for sale at the ExploraStore in Exposition Park's California Science Center.
The visible man (Skilcraft, $24.95) Human organs are connected in a clear jigsaw puzzle. Its success spawned Visible Dogs, Brains and Cows. "It shows that we aren't that different."
the ultimate science kit (DK Publishing, $99.95) In more than 100 experiments, kids learn how and why rainbows refract light, crystals grow and volcanoes erupt. "I would have played with this."
Titan base erector set (Meccano, $119.95) A staple for budding engineers, it allows kids to build intricate robots. "To see a finished product that works is extremely satisfying."
