thank you so much your explanation is so clear!

Thank-you for this! Well explained and easy to understand.

Glad it was helpful!

Thank you very much, It is really informative video!! Actually I'm planning to make an artwork using osmosis pressure. May I ask something? If the water moves to the tube, when the solution in the tube almost touches the top of the cylinder, would the solution overflow out of the tube? I want to let the solution come out of the tube and drop down as droplets.

[@sciencemusicvideos]

I think it would! If your artwork works, please send me a video! It will be a great demonstration of osmotic pressure.

@@sciencemusicvideos Thank you for the answer, I will definitely send you!

The only thing you need to remember with osmosis is high concentration moves to the place there was a low concentration like spraying deodorant in room and not smelling it in low concentration area.

good example of diffusion...and osmosis is diffusion of water!
