Foldscope
Foldscope Instruments Inc developed a paper folding microscope and as they say on their website, their goal is to share curiosity worldwide.
Foldscope is the ultra-affordable paper microscope. It was designed to be portable and durable, while performing on par with conventional research microscopes (140X magnification and 2 micron resolution). That is strong enough to view things like bacteria, blood cells, and single-celled organisms. As well as larger things like a insects, fabrics, organic tissues, and more!
Price is a huge barrier to give people at large the right tools to go on a journey of curiosity and excitement in scientific exploration! If you think this is a good idea, go and buy one and support them to bring tools to communities around the world.
In 2019 they have reach a goal of million Foldscopes in people hands.
The same people that are behind Foldscope made also the Paperfuge that we have mentioned in a different post
