Launching marshmallows out of a vacuum cleaner, making rockets from household items, and fiery explosions galore kept several hundred Central Otago children and their caregivers entertained during a "Scientific Funomena'' in Alexandra yesterday.
The show was by Dr Graham Walker, of Australia, whose visit is part of the International Science Festival. His tour of Otago has been organised by the Royal Society of New Zealand, with assistance from the University of Otago.
Dr Walker showed how science could transform household items into rocketships and marshmallow launchers and drew gasps from the audience as he also threw flames and summoned up fireballs. His aim was to show how much fun science could be and get young people interested in a career along those lines.
