Side Walk Paint

Sidewalk paint allows kids to create an amazing design that washes away with the next rainfall!


Ages:  3+

Materials: For each cup of paint you'll need -
  • clear plastic cup
  • 1/4 c cornstarch
  • 1/4 c cold water
  • food color
  • large, child friendly paintbrush or foam brush
Procedure:
  • Depending on the age of child making the paint, pre-measure or encourage children to measure, water and corn starch and combine in a clear plastic cup.  This is best done outside because the cornstarch will be messy!
  • Mix the water and cornstarch thoroughly.  If your paint is too thick, thin it with a bit more water.
  • Kids can add drops of food color to tint their paint.  With very small children allow them to choose the single color, and add it for them (food color will permanently color fingers and clothes)  Older children can follow the formulas on the food coloring box to make a variety of paints. 
  • Turn this into an experiment by throwing away the food coloring box and challenging your kids to make as many different colors as possible.  They can record their combinations and try to replicate each others colors.

Choose a sunny day and relax while kids explore mixing colors and painting all over the driveway.  Cornstarch is non-toxic and easily cleans up with water.
