Kids will just love these fantastic chalk grenades with over 200 throws in them, each time they land or make impact, they produce a plume of colourful powder! Washable & safe, the chalk is similar to Holi powder thrown at festivals, & they're great for Bonfire Parties, where kids can get interactive with a safe, flame free explosion of colour. The powder is washable, but could stain certain fabrics, so absolutely for outdoor use only, & not for using in your best white clothes! Colours chosen at random.
