Sun Print Paper Kit – 8 Sheets | STEM Activity | 15x20cm

Sun print paper from House of Marbles creates photographic silhouettes using sunlight — place objects on the paper, expose to direct sunlight, and the areas covered by the object remain while the exposed surface changes colour. Each pack contains 8 sheets measuring 15 x 20cm.

House of Marbles is a UK toy brand known for traditional and tactile products that have genuine educational and play value. Sun print paper sits firmly in this tradition: it's a STEM activity that feels like art-making. The process uses UV light to create photographic-quality silhouette prints from leaves, feathers, shells, keys, flowers, or any flat object — the more intricate the object's outline, the more detailed the print.

The science underpinning sun printing — photosensitive chemistry, UV light exposure, image fixing — is genuinely interesting to curious children and provides a natural conversation prompt for science and nature learning. The art output is simultaneously beautiful and immediate: the process takes minutes, and the results are distinctive enough to display rather than discard.

With 8 sheets per pack at 15 x 20cm, there's enough material for a full experimental session with a child — trying different objects, different exposure times, and different compositions across multiple prints. This makes it well-suited as both a party bag filler for nature or science-themed parties and as a standalone activity gift for children who respond to making things with their hands.

Pair with our Cat's Cradle or ReCycleMe Mini Craft Kit for a craft and activity party bag combination.
