DIY projector
Turn a recycled cardboard tube into a mini projector for simple shadow shows, storytelling and STEM learning!
With just a cardboard tube, cling wrap, tape, markers, and a torch, kids can make their very own projector.
Draw a design or character on the cling wrap, attach it to the tube’s end, shine a torch through it, and watch the image project onto a wall or ceiling.
This activity introduces the basics of light, shadows, and projection in a fun and engaging way. You can experiment with distance, angles, and layering multiple designs to see how the projections change.
It’s a simple, low-cost craft-ivity and perfect for encouraging curiosity around STEM concepts, creativity, and problem-solving!
Materials
Prep / make
Step 1:
Gather all materials on a table or tray.
Step 2:
Cut a piece of cling wrap slightly larger than the tube’s end.
Step 3:
Find a wall or flat surface to project onto.
Step 4:
Keep markers, tape, and torch within easy reach for quick access during play.
Play
Step 1:
Tape the cling wrap securely over one end of the cardboard tube, making sure there are no wrinkles for the light to refract.
Step 2:
Draw a design or character on the cling wrap. The bolder the mark the better - we find Sharpies work really well.
Step 3:
Shine the torch through the open end onto the wall or ceiling.
Step 4:
Experiment with distance, angles, and different drawings to see how projections change.
Step 5:
Take turns creating new designs and projecting them.
Extend
Colour Fun: Add coloured markers or layers to make vibrant projections.
Story Time: Project characters or scenes to create a mini story theatre.
Science Exploration: Experiment with shadows by placing objects between the torch and wall.
Angle Challenge: Change the tube angle or distance to see how it affects size and sharpness.
Mini Cinema: Combine multiple tubes for multi-character projection shows.
