Step 1
Gather all the materials from the list and set them on a clear workspace.
- 2
Step 2
Use the ruler and pencil to mark a narrow rectangular dispensing slot near the bottom center of one side of the box.
- 3
Step 3
Cut out the dispensing slot with scissors and ask an adult to help with the craft knife for neater edges.
- 4
Step 4
Draw a round viewing window above the slot that is big enough to show a spinning wheel.
- 5
Step 5
Carefully cut out the viewing window with the craft knife while an adult watches and helps.
- 6
Step 6
Cut a cardboard circle slightly smaller than the inside width of the box to make the gacha wheel.
- 7
Step 7
Cut a small notch in the rim of the wheel that is sized to hold one capsule at a time.
- 8
Step 8
Push a pencil through the center of the wheel to create an axle.
- 9
Step 9
Slide the wheel into the box behind the viewing window and tape the pencil ends to the inside walls so the wheel can spin freely.
- 10
Step 10
Cut a small flap or hole in the top of the box to act as a hopper for loading capsules.
- 11
Step 11
Decorate bottle caps or small paper capsules with colouring materials and shiny stickers to make them look like celestial pods.
- 12
Step 12
Cut many tiny star tokens from shiny paper or draw stars on plain paper and cut them out.
- 13
Step 13
Place one star token inside each decorated capsule and drop the filled capsules into the hopper.
- 14
Step 14
Turn the pencil axle to spin the wheel and watch a capsule dispense through the slot to test your Celestial Gacha.

Fun facts
How do I make a cardboard celestial gacha box and test it?
To make a cardboard celestial gacha, trace and cut a dispensing slot and build a rotating drum or sliding tray inside a sturdy box. Create capsules from toilet-paper rolls, plastic eggs, or bottle caps and decorate them as planets. Add a simple release using a dowel or tube so one capsule drops at a time. Paint stars and space motifs, load tokens, then adjust the slot and test repeatedly to ensure smooth dispensing.
What materials do I need to create a celestial gacha box?
Youâll need a sturdy cardboard box, scissors or a craft knife, ruler and pencil, glue or hot glue, and tape. Use a wooden dowel or skewer for the dispenser axle and small capsules (plastic eggs, bottle caps, or toilet-paper-roll sections). Prepare paper or foam star tokens, paints/markers, stickers, and glitter for decoration, plus optional clear tape or a paper straw for a dispensing tube. Include adult supervision and a cutting mat for safety.
What ages is a cardboard celestial gacha box suitable for?
This activity suits children aged five to twelve. Young children (five to seven) enjoy decorating capsules and testing drops with close adult help for cutting and assembly. Children eight to twelve can build the dispenser with minimal supervision and try more complex mechanisms like a rotating drum or prize sorting. Toddlers under five can decorate large tokens but should not handle small choking-risk parts or sharp tools.
What safety tips and creative variations should I consider for the celestial gacha?
Always supervise cutting and hot-glue use, keep small capsules away from children under three, and test dispensing for pinching points. Use non-toxic paints and let decorations dry fully. For variations, try glow-in-the-dark stars, numbered surprise challenges, reward tokens, a solar-system theme with planet facts, or a magnetic dispenser. These ideas boost STEM learning, fine motor skills, and storytelling as children design and use the gacha.
Watch & Learn
Need help?
What can I use instead of a craft knife or bottle caps if I don't have them?
If you don't have a craft knife, ask an adult to use a utility knife or carefully cut the viewing window and dispensing slot with strong scissors, and replace bottle caps with folded paper capsules or large beads when decorating your celestial pods.
Why won't the wheel spin freely or capsules get stuck, and how do I fix it?
If the wheel won't spin or capsules jam, check that the pencil axle isn't taped too tightly to the inside walls, loosen or reposition the tape so the wheel rotates freely, and widen the wheel notch or dispensing slot slightly so only one decorated capsule passes through at a time.
How can I adapt this Celestial Gacha for younger children or older kids?
For younger children, have an adult cut the slot and window and use large decorated bottle caps and oversized star tokens for easy handling, while older kids can cut the cardboard wheel themselves, make a precise notch and experiment with multiple notches or finer decorations like painted constellations.
What are simple ways to enhance or personalize our Celestial Gacha?
Enhance your gacha by painting galaxy patterns on the box, adding glow-in-the-dark stickers to the star tokens, swapping the viewing window for clear plastic for a cleaner look, or creating themed prize tiers inside the decorated capsules.
