How to Make a Pinhole Projector: NASAs Tips and Tricks
On August 21st, 2017, a rare celestial event called the Great American Eclipse enthralled viewers across the US. Millions of people across the country put on their special eclipse glasses or used pinhole projectors to watch the moon pass in front of the sun. If you missed out on the chance to witness this awe-inspiring event, dont worry. Another one is expected to occur in 2024. But this time, make sure you have your own pinhole projector ready to use!
Pinhole projectors are a safe and easy way to view eclipses and other solar events. And the best part is, you can make them at home with just a few simple materials. In this article, well walk you through the process of making your very own pinhole projector, using tips and tricks provided by none other than NASA!
Materials Youll Need:
- Two sheets of white cardboard or paper
- A small, sharp pin or needle
- Aluminum foil
- Scissors
- Tape
- A long cardboard tube (optional)
Making Your Pinhole Projector:
Step 1: Take one piece of cardboard or paper and poke a small hole in the center using a pin or needle. Make sure the hole is small and neat - it should be no larger than the tip of a ballpoint pen.
Step 2: Cut a square of aluminum foil thats a little larger than the cardboard piece. Tape the foil over the hole in the cardboard, making sure its smooth and flat.
Step 3: Use your second piece of cardboard to make a screen for your projector. Cut out a square or rectangle thats big enough to cover the foil-covered hole on your first piece of cardboard.
Step 4: Tape the two pieces of cardboard together along one edge, making sure theyre aligned properly. Now, you can use your pinhole projector to view the sun! Hold the cardboard with the pinhole towards the sun, and move your screen around until you see a clear, inverted image of the sun on the screen.
Bonus Tip: If you have a long cardboard tube, you can use it instead of the second piece of cardboard to make a more stable and precise pinhole projector. Simply tape the first cardboard piece with the pinhole onto one end of the tube, and use the tube as a handle to hold the projector to your eye.
Remember, its important to never look directly at the sun without proper eye protection, as this can cause permanent eye damage. Making a pinhole projector is a simple and safe way to view solar events, like eclipses, without putting your eyes at risk. And with these NASA-approved tips and tricks, youll be able to make a pinhole projector thats both effective and easy to use! |
