Thousands flock to science expo
About 4000 people have taken a crash course in science, learning scientific secrets from sensory perception to walking on water.
The University of Otago Science Expo in Dunedin, part of the New Zealand International Science Festival, saw thousands of adults and children get hands-on in a variety of scientific experiments over Sunday and Monday.
One of the biggest drawcards of the expo was student Zin Aung, 25, who braved the chilly temperatures to model the human muscular system in body paint.
Nicole Heydenrijk, director of Body FX Body Art, took more than four hours to paint the entire muscular system on to Aung, who kept warm with several cups of coffee and a small fan heater.
A brave few walked on water in one experiment that saw a cornflour and water mixture suspended in a bath tub.
The molecular makeup of the mixture causes it to harden under pressure, so budding scientists could walk across the surface.
Others tested their balance by standing on one leg with their eyes closed on a soft balance board.
Balance, for sighted people, is based partly on visual cues.
With sight taken away, most fell over within seconds.
The festival runs until Saturday at locations throughout Dunedin.
