I love this!
I saw this online a few days ago, but this is the first chance I have had to post it.
In this TED talk Manu Prakash shows a microscope that folds like origami. It is practically indestructible and it is inexpensive to make.
PrakashLab at Stanford University is currently looking for beta-testers for Foldscope. I hope they get the publicity they need to make mass manufacturing of optical microscopes a reality.
This could have a major impact on global health.
It would also be super cool if all K-12 students were able to have their own microscopes. What a great resource!
