Introduction: Laser Microscope. Simple But Awesome Project

About: I love writing, I make video in MY UPLOADED VIDEOS channel in Youtube for my instruction, and i love making something. www.instagram.com/balsuryana

Summer is fun and making something its super fun! In this day i will show you how to make Microscope using a Laser pointer. This is fun project and easy project ! anyone can build this!

Its can use to see a bacteria, small object and anything. The cost to build this is under 1 dollars!

You can use it for school project, science project and etc. Ok lets make it

Step 1: You Needs:

  • Laser pointer
  • 1 Toothpicks
  • Some tape
  • Rubber eraser
  • Old Card for make the holder

Step 2: Simple

  • Take laser, card, and some tape
  • Tie the laser to the old card with tape like image
  • And Next....

Step 3: The Eraser

  • Take the eraser and toothpick
  • Insert the toothpicks into the eraser like image
  • And finish!

Step 4: Installations

  • Place the eraser in front of the laser
  • Drop a water at the end of the toothpick
  • Turn on the laser and look the life on the drop of water

you're welcome. And thanks for look my works

I am skeptical this is resolving down to the size of bacteria. I would suggest trying it with some cheek cells from your mouth suspended in water. They are easily recognized and the size and shape of the nucleus is predictable. Bacteria need 200-400x and I doubt a water droplet has this magnification - just guessing.

Thank you for your suggestion. Yes, I believe that the cheek cells from mouth has that predictable shape. Thank you :)

The video looks like Brownian motion of particles in suspension in the droplet.

Neat trick. The laser beam expands using the water drop as a lens. This is how the first microscopes were done - without glass lenses!
Then the laser turns it into a projector.

You should probably mention it projects onto the wall

Another good thing to mention is don't point laser into eyes

Legaly compliant laser pointers are too weak to do any damage - it's still unpleasant though.
