On a sunny day, when you want to get the kids out the house and into the fresh air, clean out an old spray bottle that can create a mist, and fill with water. Tell your kids to go outside and spray towards the sun until they notice a surprise! A small rainbow will form in the mist created, and the kids learn about how rainbows are made, as well as the fun of creating one at home!

2. Hidden rainbow

Tell your kids to use crayons to colour a rainbow filling a whole paper in the right order (red, orange, yellow, green, blue, indigo, violet). Then to cover that same paper over the crayon with black water-based paint. Let dry, then with a toothpick or BBQ skewer, the kids can scratch out any design or drawing they desire, leaving behind a beautiful effect and a magical surprise!
