Product Details

It's spring break. Time to cast off the winter doldrums and embrace the bright new season! Celebrate the arrival of spring with six fun demonstrations: • An oscillating chemical reaction alternates between frigid blue and sunny yellow, just like the unpredictable spring weather. • A rainbow suddenly appears, then just as quickly disappears, when alternating colorless solutions are mixed. • Shake a yellow solution and the color changes from yellow to red to spring green, the color of new plant growth and one of the prettiest colors of the year. • Spray a special misting solution on paper flowers and watch them bloom—April showers bring beautiful May flowers! • A blue flower changes to pink as the weather changes and the humidity rises. • As spring break approaches, all thoughts turn to...VACATION! Sit back and enjoy a chemical “sunset” on your favorite tropical beach.
