Step 1: Get a magnifying glass and clear plastic sheet or windowpane Step 2: Position the magnifying glass so the beam of light shines onto the plastic surface Step 3: Move the sheet until you find an image on it Step 4: Turn your projector towards a wall or screen Step 5: Try to create an image on the screen by moving the sheet as you would move a slide with your hand.   Image source: https://www.lg.com/ Here is a brief on what the article is going to be about: "This article will tell you how to make a projector with a magnifying glass. You can use it for group presentations or just as an activity”. A projector can be great if you want to show something on the wall, but they're often expensive and hard to find. Luckily, it's easy in theory (and pretty easy in practice) to m
