Transform your dark room into a dazzling rainbow wonderland with this fun and easy DIY Rainbow Light Show project! Using simple materials like cardboard tubes and markers, you can create mesmerizing light wands that project colorful patterns onto your walls. Perfect for kids, science lovers, or anyone who enjoys creative crafts, this Rainbow Light Show activity blends art and science in a magical way.
Why This Rainbow Light Show is Educational & Fun
This Rainbow Light Show isn’t just visually stunning—it’s also a great way to teach kids about light refraction, color mixing, and how light travels. As they experiment with different patterns and colors, they’ll see firsthand how light interacts with translucent materials. Plus, it encourages creativity as they design their own unique light shows!
For older kids and adults, this can be turned into a mini science experiment. Try overlapping different colored tubes to see how secondary colors form, or test how distance from the wall affects the size and brightness of the projections. The possibilities for learning and play are endless!
Materials Needed
Before you begin, gather these supplies:
- Cardboard tubes (toilet paper or paper towel rolls)
- Cling wrap (stretched tightly like a drum)
- Permanent markers (neon colors for extra brightness!)
- Rubber bands or tape
- Flashlight or phone light
- A dark room (the darker, the better for maximum effect!)
Step-by-Step Method
Make the “Lens”
- Cut a piece of cling wrap large enough to cover one end of your cardboard tube.
- Stretch it tightly over the opening and secure it with rubber bands or tape.
Color Burst
- Use permanent markers to draw bold designs on the cling wrap. Try:
- Stripes for classic rainbow effects
- Swirls for a hypnotic look
- Polka dots for playful patterns
Light It Up
- Turn off the lights and make the room as dark as possible.
- Shine a flashlight or phone light into the open end of the tube.
- Move, rotate, or wave the tube to see your colorful designs dance across the walls!

FAQs
Q: Can I reuse the cling wrap?
A: Yes! Just wipe off the marker with rubbing alcohol and let it dry before reusing.
Q: What if my cling wrap isn’t tight enough?
A: Use extra rubber bands or tape to keep it stretched firmly—wrinkles can blur the colors.
Q: Can I use something besides cling wrap?
A: Try wax paper for a softer glow or clear plastic sheets for sharper designs.
Q: Why do the colors project so brightly?
A: The light passes through the translucent cling wrap, diffusing the colors onto the wall like a mini projector!
Take It to the Next Level: Advanced Light Play
Once you’ve mastered the basics, why not experiment with more complex designs? Try cutting shapes out of black construction paper and taping them over your colored cling wrap to create silhouette effects—you’ll project both colors and shadows for an even more dynamic display. For a moving Rainbow light show, attach your tube to a slow-moving fan or turntable and watch as the colors swirl automatically across your walls. Older kids might enjoy incorporating programmable LED lights that change colors, syncing their light show with music for a full sensory experience. The only limit is your imagination!
This project proves that with just a few household items, you can create interactive art, science experiments, and unforgettable family memories. It’s amazing how something as simple as a cardboard tube can transform into a magical light instrument—perfect for bedtime stories, dance parties, or just quiet moments of wonder.
