Copernicus DIY Bouncing Ball Kit

The Copernicus DIY Bouncing Ball Kit lets makers create six vibrant, multi-coloured, high-bouncing balls. Users simply mix and layer colours inside the supplied mould. The set is designed for children, teens and adults who enjoy hands-on craft activities. Instructions are included to guide the process.

Sustained play behaviour

Each ball retains its bounce and colour layering through repeated impact on hard surfaces. The moulding material sets firmly, so finished balls resist cracking or flattening during extended sessions. No electronic components or moving parts are involved, so performance does not degrade with heat or battery drain. The activity scales from quick solo experiments to longer group workshops.

Setup checklist

Confirm the intended users meet the recommended age range of child, teen or adult before ordering. Ensure a clean, flat workspace is available for mixing and moulding steps. No power supply, tools or additional hardware are required beyond the contents of the kit. Check that the recipient has no known sensitivity to the colouring agents used.

Questions about this item

Will the balls leave a sticky residue on surfaces after repeated indoor bouncing?

The kit uses dry polymer granules that solidify in the mould; once formed the balls are dry to the touch and leave no residue on floors or walls.

Are any household supplies such as water, bowls or measuring spoons required to complete the kit?

Everything needed is in the box — pre-measured coloured granules and the mould — so no extra ingredients or tools are required.

Can younger siblings safely handle the finished balls if they are under the recommended age of eight?

The finished balls are solid, non-toxic and large enough not to be a choking hazard, but adult supervision is still advised for children under eight.
