Have a go at making your own Magic Rainbow Milk. Kids of all ages will love it! Its cheap, quick and easy to set up and if you do it outside (highly recommended!), theres not that much mess to clean up afterwards.
Have a go at this super easy summer sensory play activity. Kids will have lots of fun playing outside with these coloured ice cubes on a sunny day. They're great for playing with at bath time and on highchair trays too!
