Nailmatic DIY: Crackling Bath Bomb & Soap Set

If your kid loves a project (and also loves making a bit of a mess), this Nailmatic DIY Crackling Bath Bomb & Soap Set is basically their dream afternoon. It’s part science kit, part spa session, and very much “look what I made!” energy. Designed for ages 7+ (with you hovering nearby pretending not to take over), it gives them everything they need to make one fizzy bath bomb and a sweet little cat-shaped soap.

Inside the box you’ll find a 50g soap bar with a reusable natural latex mould, plus coloured baking soda and citric acid to whip up a proper fizz-the-house-down bath bomb. It’s fun, sensory, hands-on, and gives them a tiny crash course in how their favourite bath treats are actually made. All made in France, skin-kind, and gently formulated so it feels like a treat rather than a chemistry experiment gone wrong.

Perfect for gifting, rainy-day entertainment, or just adding a bit of sparkle to bathtime, it’s one of those kits that keeps them busy and leaves you with something cute and useful at the end. A win for everyone.
