Experiment #2: Mix colors together

What you need:

scissors and clear red, blue, and yellow plastic sheet

Cut the sheets into strips of the same size.

Place yellow and blue strips on a white surface.

Green appears where they overlap and the colors mix.

Add a red strip to begin a pattern of squares.

See how red and yellow mix to form orange.

Add another red strip.

See how purple forms where red and blue mix.

Add more strips. Red, blue, and yellow mix to form 3 other colors.

Where the same colors overlap, bright yellow, red, and blue form.
