Minimalist Laser Microscope

HOW IT WORKS
Taking advantage of water's surface tension, by shining laser light through a suspended droplet (for which we use a syringe), you can achieve a projection of what's inside a water sample (ideally, stagnant). The suspended droplet acts as a lens and amplifies the image. Instead of having a blurry shadow, which you would obtain by using just a regular light source; in this case, the projection will be relatively clear, due to the nature of laser light. Here, we use an easily-sourced class III laser (a cat training laser pointer will do!). Photons emitted by a laser are coherently in phase, such that refraction via this light source produces a higher-fidelity projection. This is the principle behind our laser microscope. Make sure you NEVER look directly into the laser source! Long-term exposure can damage your eyes, better be safe than sorry! This build will avoid part of this risk by housing the source and diffracting the light.
