Need a quick, no-prep science activity? This colourful Rainbow Walking Water Experiment is your time-saving solution! Just print, gather a few simple materials, and you’re ready to amaze your students without the stress.

Make learning the scientific method fun, colourful, and hands-on with this engaging Rainbow Walking Water Experiment, designed especially for Prep to Year 2 students!

This resource includes 14 print-and-go activity pages in both AUS/UK and USA spelling versions (colour/color), guiding students step-by-step as they watch water “walk” between cups, mix to create new colours, and form a magical rainbow effect. Students will observe, predict, record, and explain the science behind capillary action in a way that’s age-appropriate, visual, and meaningful.

The experiment is quick to set up using everyday materials (just clear cups, water, paper towel, and food colouring). The results are gradual but mesmerising. As the colours travel and blend, students will be hooked on discovering what happens next! Clean-up is simple, and everything else you need is ready to print and go. Just grab your materials, display the instructions, and you’re all set.
