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.
Kids LOVE slime and this is such an easy messy play and sensory play activity to make using simple household ingredients. Your kids will have lots of fun stretching it, moulding it, rolling into balls, throwing it into the air and letting it splat on the table!
Have a go at making your own glue sponge for the kids to use. Homemade glue sponges are super cheap to make and really easy to put together at home. They also last a surprisingly long time and stop you from having sticky glue everywhere! Glue sponges are great to use for your kids arts and crafts projects and can be sealed up ready for use next time.
