Why You’ll Love This Project
This DIY Rainbow Light Show is more than just a craft; it’s an educational experience that captivates children and adults alike. By constructing a simple projector using cardboard tubes and cling film, participants can create mesmerizing light patterns that demonstrate the dispersion of light into various colors. It’s an excellent way to encourage curiosity about science while enjoying a fun and artistic activity.
Materials Needed
To create your own Rainbow Light Show, gather the following materials:
- Empty cardboard tubes (toilet paper or paper towel rolls)
- Cling film (plastic wrap)
- Rubber bands or tape
- Permanent markers (variety of bright colors)
- Scissors
- Flashlight or phone light
- Craft stick or pencil (optional, for support)

Necessary Tools
- Scissors: For cutting cling film and shaping the cardboard tube if needed.
- Markers: Permanent markers work best on cling film to create vivid colors.
- Flashlight or phone light: Serves as the light source to project the colored patterns.
- Rubber bands or tape: To secure the cling film onto the cardboard tube.
Step-by-Step Instructions
- Prepare the Film Lens: Cut a small square of cling film large enough to cover one end of the cardboard tube with a little extra around the edges.
- Color the Film: Using permanent markers, color bold rainbow designs directly onto the cling film. Be creative with stripes, swirls, or dots!
- Attach to Tube: Stretch the colored cling film over one end of the cardboard tube. Secure tightly with a rubber band or tape so it’s smooth and taut.
- Insert Light Source: In a dark room, shine a flashlight through the open end of the tube, aiming the beam through the colored film.
- Create the Light Show: Slowly rotate the tube or move the light around to project dancing rainbow patterns onto walls and ceilings!
- Optional Handle: For added control, insert a craft stick or pencil into the bottom of the tube as a handle.

Pro Tips for Success
- Use Bright Colors: The more vibrant your marker colors, the more vivid the projected patterns will be.
- Smooth Surface: Ensure the cling film is stretched tightly over the tube to avoid wrinkles that can distort the light patterns.
- Experiment with Designs: Try different patterns and color combinations to see how they affect the projected light.
- Dark Environment: Perform the activity in a dark room for the best visual effect.walktalkplay.com

Q: Is this activity safe for young children?
A: Yes, but adult supervision is advised, especially when using scissors and handling the flashlight.
Q: Can I use colored cling film instead of coloring it myself?
A: Yes, pre-colored cling film can be used, but creating your own designs adds a personal touch and educational value.
Q: How can I make the light show more dynamic?
A: Try moving the flashlight closer or farther from the tube, or rotate the tube to change the patterns.
