Tip: Make sure you’re wearing clothes that can get messy!
Place the tarp on the floor (or set up in your backyard)
Tape down a length of paper or several sheets of newspaper in a long row
Set up your paint tray with three primary colours
Dip the car wheels into one colour of paint and roll it on the paper. This may also turn into finger painting, which is OK!
Dip a different car into another colour and see what happens when you roll it over the tracks that are already there. Do you see a new colour appear? This is called a secondary colour.
Once you’ve made a colourful masterpiece, it’s time for a car wash! Clean your cars in buckets of warm soapy water and dry them off with paper towels. Tip: the car wash is just as much fun – leave extra time for this part!
