"Quantum physics is the physics of things that are really, really small," co-host Luke Trainor said.
"When you get down to the smallest scales we have, things start to behave very weirdly.
"Unfortunately it is quite difficult to demonstrate this so we’re going to the closest things we see to quantum physics in our daily lives, which are light and electricity and we do have a lot of tools and demonstrations around those topics."
As a post-doctoral fellow at the University’s Dodd-Walls Centre for photonic and quantum technologies, Mr Trainor does physics research as a job.
He and Tūhura’s Jessa Barder led an audience of about 30 local adults and children through two sessions of explanations and demonstrations.
The duo began by giving out special prismatic glasses which split ordinary "white" light into the seven colours of the spectrum.
They then shone small lasers through the lenses to show light’s colour depended on its wavelength.
Other demonstrations included a superconductor frozen in liquid nitrogen to make it hover over a magnet.
"Tūhura and University of Otago work together really closely to do science engagement across the country," Mrs Barder said.
"We are partners on an international competition to bring science and art together called Quantum Shorts, which is run out of the Centre for Quantum Technology of Singapore.
"We wanted to bring some fun science about quantum physics and a talk by Luke out on a tour into the communities and we’re finding engagement is very positive."
