Space Small World in a Box
Black paper, foil balls and a torch make a galaxy on the living room floor.
By WonderCraft Kids Editorial Team, Editorial team · Updated 22 July 2026
Small worlds give pretend play a stage. A shallow box lined in black, a handful of foil planets and a torch turns into an hour of narrated space missions — and the building of it is half the fun.
What you need
- A shallow box lid or under-bed tray
- Black paper or paint
- Aluminium foil
- White paint or chalk for stars
- A small torch
- Lego figures or peg dolls as astronauts
Step by step
- 1
Line the box with black paper or paint it black and let it dry.
- 2
Flick white paint from a brush for a star field, or dot chalk stars on.
- 3
Scrunch foil into planets and moons of different sizes.
- 4
Add craters by pressing a marble into a foil-covered ball of paper.
- 5
Turn the lights off and hand over the torch.
- 6
Ask for a mission: what are the astronauts looking for today?
What kids learn
Narrative play
Inventing a mission and narrating it is oral storytelling — strongly linked to later writing ability.
Space vocabulary
Orbit, crater, moon, mission. Words stick when they belong to an object in their hands.
Light and shadow
A torch in a dark box demonstrates how the moon is lit from one side at a time.
Make it easier
Skip the painting; black paper and foil balls are enough for a four-year-old to start playing.
Make it more challenging
Research the real planet order and make them to scale in size, labelled on flags.
Safety and supervision
- Supervise torch use and avoid shining it in eyes.
- Foil edges can be sharp — scrunch them fully round.
- Keep marbles and small parts away from under-threes.
Adult supervision is required for every activity on this site. Read our full child safety guidelines.

Dinosaur jungle with shredded paper, a farm with oats, an ocean with blue rice.
