Have a go at creating your own mini aquarium in an old jam jar. Its easy to do and the kids will love how the glitter and sea creatures swirl around inside the jar. The aquariums also make great party decorations and party favours for kids to take home instead of a party bag.
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.
