A 3-D printer will print out an artificial hand and visitors will be able to walk through a large inflatable brain at the University of Otago's latest Science Expo this weekend.
The two-day expo is being held at the university's St David lecture complex, starting at noon on Saturday, as part of the latest New Zealand International Science Festival.
More than 40 interactive exhibits would feature at the latest free expo, compared with about 35 last year, an expo organiser, Rose Newburn, said.
Many university departments and centres were participating, including the design for technology section and computer science department, which will operate 3-D printers, and the Brain Health Research Centre, which is providing the model brain.
Another event, next week, will tell members of the public about Otago University research.
A free session of ''Two Minute Talks: Young Women in Science'', will start at 7.15pm next Tuesday at the Wall Street mall, in George St, also as part of the festival.
Twenty young women, ranging from undergraduates to postdoctoral researchers and lecturers, will present their science in just two minutes, event organiser Dr Angela Clark said.
Leading New Zealand women of science, including Dame Elizabeth Hanan, Prof Jean Fleming and Otago Regional Council member Gretchen Robertson, will also give keynote talks.
