Turn the World on its Head!
These amazing Reversing Goggles allow you to view the world upside down! The plastic goggles hold two Dove prisms, which invert the image.
Back in 1896 the American scientist George Stratton conducted an experiment to see what would happen if he viewed the world through an inverting prism. He found that after 4 days, his brain started to compensate, and he could see the world the right way up again.
The kit includes a lightweight, ventilated plastic housing, two prism holders made from MDF (medium density fibreboard), two high quality Dove prisms in lightweight plexiglass giving a 35x20mm view, plus a small file for smoothing edges.
A small amount of assembly is required. You will need a protractor in order to measure a right angle and some 2 component glue that hardens quickly.
