We experiment with surface tension again
My family and I experiment with surface tension again.
We put water into the petri dish and threw pepper on top. I saw the pepper floating, I could imagine the pepper is like the water atoms holding onto each other. I dropped the soap into the petri dish. The pepper shot across the petri dish. It was so strange to see this happen. The pepper symbolizes the water tension, so when we added the soap to the petri dish it weakened the water tension, and that is how the pepper shot across the petri dish.
How cool is this!!

This is such an interesting experiment Edmon and you have explained the concept of surface tension so well. Thank you for sharing this on your blog.
ReplyDeleteWow this such an instresting post its weaird how the peper just floats away very quickly. Did you do this exprment to highlight the inportance of washing our hands?,
