How to Turn Your iPhone Into a Black Light

Turning your iPhone into a black light involves a simple DIY approach. Here’s how you can do it:

  1. Materials Needed:
    • Your iPhone (or any smartphone with a flashlight).
    • Transparent tape (preferably clear).
    • Blue and purple markers (sharpies or similar).
  2. Steps:
    1. Cover the flashlight lens of your iPhone with a small piece of clear tape.
    2. Color over the tape with a blue marker. Let it dry for a moment.
    3. Add a second layer of tape over the first one.
    4. Color this second layer with the purple marker.
    5. Optionally, for increased effect, you can add a third layer of tape and color it blue again.
  3. Use It:
    • Turn on the flashlight function on your iPhone. The light should now have a hue that mimics a blacklight.
  4. Limitations:
    • This DIY blacklight won’t be as effective as a real blacklight. It may not work for all the purposes that a standard blacklight would.
    • It’s more of a fun experiment and might help in some cases to highlight white or fluorescent colors, but it won’t have the full effect of revealing hidden stains or marks that a real blacklight would.
  5. Safety Note:
    • Be careful not to damage your phone with the marker ink. If you’re concerned about this, you might want to test on a small, inconspicuous area first or use a phone case.
  1. Enhancing Effectiveness:
    • The intensity of the colors you use can impact the effectiveness of your DIY blacklight. Darker shades of blue and purple are usually better.
    • Make sure the tape layers are smooth and free of air bubbles for a more uniform light emission.
  2. Applications:
    • This DIY blacklight can be used for fun activities like reading invisible ink messages or illuminating fluorescent materials in the dark.
    • It’s also a great tool for parties or decorations, especially if you’re aiming for a certain ambiance.
  3. Experimentation:
    • Feel free to experiment with different numbers of tape layers or shades of color to see what works best for your needs.
    • You can also try using different colored lights available on some smartphones to see how they affect the outcome.
  4. Cleaning Up:
    • Once you’re done using your makeshift blacklight, you can easily remove the tape and marker ink from your phone’s flashlight.
    • Using alcohol wipes or a bit of rubbing alcohol on a cloth can help remove any marker residue.
  5. Consider a Real Blacklight:
    • If you find yourself frequently in need of a blacklight, consider purchasing a real UV blacklight flashlight. They are relatively inexpensive and much more effective than a DIY solution.
  6. Creative Uses:
    • Beyond the typical uses, you can get creative with your DIY blacklight. For example, you can create art that only reveals itself under blacklight or set up a unique game for kids that involves finding objects that glow under the blacklight.
  7. Educational Aspect:
    • This can be a great educational tool to teach children about light, colors, and fluorescence. It’s a hands-on experiment that can make learning about physics and optics more engaging.

Remember, while this DIY method can be a fun and educational experiment, it doesn’t replace the effectiveness of a real blacklight, especially for professional or more demanding applications.
