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.
An hour of assembly is required. You will need a protractor (ot tri-square) in order to measure a right angle and some "super-glue gel" that hardens quickly. We recommend buying matt black paint & suitable brush to black-out the peripheral surfaces (see image). This will increase the quality of the view better than using black electrical tape (which reflects light internally & traps air).
The assembly instructions are downloadable below, please take a look so you are confident of the assembly.
