Stretch two rubber bands from top to bottom over each cup to hold flowers in place.
Place the plastic cups onto a flat surface and fill each with a different color of Liquid Watercolor™.
Clip flower stems at an angle on the bottom and place them in each cup.
Leave the flowers out to absorb the color. Some flowers will absorb the color overnight, while other flowers may take longer.
Enjoy the observation process, as well as the final flower colors!
