Your race, your rules. Every rock is a green light for full-throttle bath colour. Challenge accepted! Drop a bath rock into the water and watch the bath change colours as your little one’s next Hot Wheels™ adventure begins. Every bath is a new challenge, and great adventures begin with imagination.

Each tin holds a set of 24 bath colour rocks, coloured with food-grade colourings. They fizz as they dissolve and turn the water a new colour right before their eyes. They rinse away fast with no tub stains, so clean-up is as quick as the race. They come in a collectable Hot Wheels™ tin from Sydney brand Nourish by Nature.

0 to imaginative in 3 seconds flat.

Ingredients: Sodium Bicarbonate, Citric Acid, Sodium Carbonate, Sodium Chloride, Maltodextrin, Food Grade Colourings (D&C Red No. 33, or FD&C Blue No. 1, FD&C Yellow No. 5), PEG-400, Aqua.

Safety and usage: For external bath-time use only, not for consumption. Adult supervision required at all times during bath play. Ensure rocks are fully dissolved before children enter the bath. Rinse promptly after use. Keep away from eyes.
