engineering tricks
Every day when I go out to walk through a park where is a small fountain, nothing unusual..let’s look at the pictures with this fountain.
There is a ball on that surface, and water comes from underneath the ball. When I came closer I noticed that the ball seems to be floating on that surface. Curious of me, I touched the ball to see what material is made and ..surprise ..the ball as well as that surface were made from granite. And again the ball was floating… I am an engineer, my best guess would be that the water pressure keeps that granite ball floating. Do you think is it so, or is there another trick?
