DIY Light Box for Kids: A Simple Project for Rainy Afternoons

A rainy afternoon doesn’t have to mean boredom. A DIY light box is a brilliant activity that keeps kids entertained for hours, and it doubles as a tool they’ll use again and again for drawing, tracing, and creative play. Read ahead to find out how to build one at home.
What You’ll Need
The key material for this project is a sheet of clear or frosted acrylic. It’s lightweight, safe for home use, and lets light pass through evenly, which is exactly what you need for a light box. Ordering it cut to size saves time and means there’s no awkward cutting at home.
Simply Plastics stocks acrylic sheets in a range of sizes and finishes, so you’ll find something that fits your box without much fuss. For everything else, you’ll need:
- A shallow wooden or cardboard box (a shoebox works well)
- A strip of battery-powered LED fairy lights or a small LED panel
- A sheet of clear or white acrylic to sit across the top
- Strong adhesive or small corner brackets to hold the acrylic in place
- Optional: coloured acrylic sheets for a fun tint effect
Putting It Together
Start by placing your LED lights inside the box, spread out as evenly as possible across the base. If you’re using fairy lights, coil them loosely instead of bunching them together, as this will give a much more even glow.
Once the lights are in position, fix the acrylic sheet flat across the top of the box. Small corner brackets or a thin bead of strong adhesive will keep it secure and flush with the edges.
How Kids Will Use It
Children can place thin paper or tracing paper on top of the lit surface to trace drawings, letters, or shapes. It’s a great way to practise handwriting, copy illustrations, or experiment with light and colour.
Swapping in a coloured acrylic sheet on top will create different tinted effects across the surface. Kids tend to find this part genuinely exciting, and they’ll want to try every colour they can get hold of.
A Few Safety Tips
Battery-powered LED lights are the safer option instead of plug-in versions, especially for younger children. Keep the lights on a low setting if they feel warm to the touch, and always supervise younger kids during the build itself.
The Takeaway
A DIY light box is one of those projects that’s straightforward to put together but offers a lot of creative potential once it’s done. Children will keep coming back to it long after the rain has stopped, and you might find yourself having a go too. As they get more confident with it, they’ll come up with their own ways to use it, from creating traced artwork to building simple shadow scenes.
