Re: I need Suggestions for experiments for 'Capillary Action'

I am so sorry to get back to you late - I hope you haven't given up on your 
project idea.  It isn't an easy one to demonstrate but maybe I can help get 
you thinking about a way.

I have been pondering your question for a while and the best I can come up 
with are tubes of different diameters.  You can get different diameter 
pipes in a hardware store and can add to the list a drinking straw and 
maybe a plastic coffee stirrer...  A liquid (colored water maybe?) will 
travel different lengths up the tube, depending on its diameter.  The 
smaller the diameter, the higher the liquid should travel on its own.

I don't know if this idea helps you get started but I will keep my fingers 
crossed.  Remember, don't get too many large sizes because you'll end up 
without any water in them once they get past a certain width (of course, 
the fun of it is figuring out what that diameter is).

Another idea is to use water with food dye, and have white carnations sit in this 
food dye instead of in regular water...the capillary action within the plant will 
eventually cause the petals to change color consistent with the dye.

Good luck!
