Did you know that you can use a laser to see tiny paramecia in pond water? We’re going to build a simple laser microscope that will shine through a single drop of water and project shadows on a wall or ceiling for us to study.

Actually, the pond water is just held in place inside the little loop of a paperclip. The video shows how to bend the paperclip.
Aurora, what was the container for the pond water when you projected it onto the wall? Did you have the pond water in a clear bottle and beam the green laser from the opposite side of the wall?
Sure, just aim it at a blank white wall and move closer or further until it comes into focus, just like aiming a flashlight on the wall. Have fun!
Aurora is it possible for you to tell me how you were able to project it onto the white wall? Thanks!
Those are most likely tiny pieces of plant.
What are the two long dark columns that go from a little bit above the cats head to the top/top right corner?
Oh no! You’re right – the wrong one was inserted here. I’ll get the right one up for you right away. Thanks for catching that – we’ve been replacing all the videos with new video players, so thanks for your eagle eye!
Is the current video correct? Because it shows nothing about a laser but it just shows the magnifying glass microscope.
