- Capillary action is a very cool science phenomenon that is essential for all life on earth! Capillary rise in small tubes is a familiar phenomenon that most of us have seen. But why is it that water rises higher in thin tubes than in thick tubes? Let's explore the physics and effects of the Capillary force. what is the capillary force? Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances). Science is Awesome, now go out and do some!
00:00 Intro to capillary action
00:19 Definition of terms for the capillary force
01:38 Testing the capillary tube set.
03:10 Discussing the correlation between boiling temperature and pressure
03:58 How do trees use capillary action if they are taller than 30 feet?
A few more terms to consider if you are looking for more information. Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube is limited by surface tension and gravity.

Science is awesome. Nature uses capillary action in ways that still aren't fully understood.
Thank you! I learned something today :)
Other than semi permeable membranes, capillary action is I think my absolute favorite subject from my bio classes. I can still hear my professors voice in my head repeating the phrase the cohesive tendencies of water and how amazing and fascinating it is to see how wonderfully intricate God has created the universe and specifically our Little world to be. We are truly fearfully and wonderfully made! It is a never-ending source of worship fascination learning and just cool, to learn about science! Wonderful video definitely hit on one of my favorite subjects! Great explanation by the way
I was curious how those tubes respond in a vacuum. Google didn’t disappoint! 😀 Very cool topic!
Um....what?! 🤯 That is so cool!! It would never have occurred to me that tree's "shouldn't work"!! Thank you for this video!!
Thanks for stopping by!
Many students have ADHD. The video would be friendly to all if it is less than 2 minutes.
where could I get this capillary tube array? I want it
Did “Shlarg” just discover air pressure??
anyone ask themselves whether water boiling out of a tube due to capillary action could turn a electrical generator turbine or does that make too much sense? I'd welcome someone telling me why this is wouldn't work.
Me about to go whack some trees to see if they will explode.
