Design an experiment to test what happens if you add multiple colors of ink to the water.
Design an experiment to test what would happen if you used food dye instead of highlighter fluid. Do you think the flowers will draw up food dye in the same way? Will you still be able to see the food dye in the flowers? Which dye do the flowers draw up more effectively?
