Smelli Gelli Baff Sensory PlayZimpli Kids
Easy one step sensory play, just add water and it will turn to goo. Comes is two fragrance of Bubble gum and Tutti Frutti.
Notes from Diany: I would strongly recommend this for a water play in a small container or tray and NOT in a full tub. The 300g packet is a lot and you can use it multiple times. From experience, It's best to try out in a manageable size when it comes to messy play.
