How to play

  1. Before you start: Line up six cups in a row. Fill the 1st, 3rd and 5th with water; leave the others empty.

  2. Color the full cups: red, yellow, blue.

  3. Fold six strips of paper towels and bridge each cup to its neighbor, ends dipping in.

  4. Ask them to predict what will happen to the empty cups, and write the guess down.

  5. Wait. The water starts climbing within a minute.

  6. Come back after ten minutes: the empty cups have filled with orange, green and purple.

What it helps with

Make it different next time

  • Use only two colors and see which mixes fastest.
  • Leave it overnight and see if the levels even out.

Cleanup: Pour the cups out and throw out the soggy strips.
