Kids will have fun making their own garden fairies, especially over summer when plants are in full bloom. Teach them the names of the flowers that you use, discuss the different shades of colour and how plants grow.
Have a go at making your own Magic Rainbow Milk. Kids of all ages will love it! Magic Rainbow Milk is cheap, quick and easy to set up and if you do it outside (highly recommended!), theres not too much mess to clean up afterwards.
