[School Festival] Handmade Planetarium Ideas (21–30)
Polyhedral Planetarium

It’s a three-dimensional planetarium made by assembling pentagonal paper with holes punched to match the positions of the stars.
You cut the paper into pentagon shapes, then draw a net of adjacent pentagons that can be folded into a polyhedron using those pentagons as guides.
After that, punch holes in each pentagon, assemble it, and place it over a small light bulb to complete the device.
You can enjoy either a pattern that faithfully reproduces constellations or a design-focused pattern with freely placed holes.
It’s also recommended to hang it and use it as a light.
planetarium lampshade

This is a planetarium that incorporates a lampshade to enclose a lamp or light bulb and diffuse the light.
Why not try making a soothing item that creates a magical atmosphere born from shadows? Cut paper according to templates featuring ghosts, pumpkins, witches, and more.
Use a hole punch and craft knife to cut out the illustrations and patterns, then clip the papers together to form a three-dimensional shape.
Attach a backing so there’s a hole in the bottom, insert a light inside, and you’re done.
It’s an idea for a planetarium that casts beautiful patterns across the night sky.
Planetarium-style light

It describes attaching a base with constellation-shaped holes that reflects light so you can project stars wherever you like.
First, stack and glue a paper cup and a paper plate together, and wrap the inside of the paper plate with aluminum foil so it reflects light.
For the constellation part, use black construction paper rolled into a pointed cone shape.
After creasing it, punch holes in the pattern of a constellation while avoiding the areas that will overlap when it’s rolled.
Finally, place the constellation piece over the paper cup and plate base, insert a light into the paper cup, and you’re done.
Choosing which constellations to project could be a fun way to add originality.
Planetarium with resin

This piece is created by layering resin with decorative elements to build up an expansive planetarium-like starry sky and the shapes of constellations.
You’ll make parts that depict constellations and parts that express the sparkle of the night sky, then layer and cure them with resin tinted in colors that evoke the night.
Another key point is stacking resin sheets and films—their irregularity produces a dreamy, floating sensation reminiscent of a nocturnal sky.
You could craft it as an ornament themed around a planetarium, or aim for gentle, light-transmitting colors to enjoy a version where you shine a light through it and project a starry sky around your room.
In conclusion
We’ve introduced many ideas and methods for creating a planetarium for the school festival.
From building the dome to choosing background music and producing the visuals, thoughtful details will expand the world of the starry sky.
Work together with your teammates to create a wonderful planetarium that will leave a lasting impression on visitors.
Surely, this experience will be etched in your hearts as a shining memory.
