MAKE contributing writer and organic chemist Sean Ragan joins us via Skype to show us his homebrew microscope which uses a bright laser to project an image through a droplet of water – microbial movie theater! Learn to build your own laser projection microscope on Make: Projects.

Electrochemistry demo from the Illustrated Guide to Home Chemistry Experiments
