Capillary Action




















Day #1


10 drops food coloring in 4 jars.
Jars are half full of water with the colors red, blue, yellow, and green.
Carnations and celery are the plants used.




















Day #2

Added daffodils.
Celery is beginning to change in blue and green.
Yellow is changing color of carnation.


















Day# 3

Celery in the red is dying.
Daffodils are opened and showing slight color change in the one in the blue jar.















Day #4

Red celery is dead celery!
Yellow carnation is yellow.
Daffodil in blue and green have dark rims.


Conclusion: Water is stilled absorbed when a plant is died or picked.

I wonder what would happen if I watered a non-picked plant with colored water.

P.S. Blogger was having problems with spacing.

Excellent pictures and commentary.
Stay away from the red dye #40. It's a killer.

Excellent science experiment! I think that I may avoid red dyes.
