A New York teacher stuns students with a truly gravity-defying experiment. Can you figure out how she did that?
A teacher has amazed her students by defying the laws of gravity.
Mrs. Madden, of Mount Kisco, New York, performed a spell experiment for her science class by turning a jar of water upside down so that not a drop came out of the opening.
Although the feat seemed magical, it was possible to use air pressure to flow into the container and trap the water inside.
A teacher from Mount Kisco, New York, taught her young students how water can defy gravity and stay in a jar even after it is turned upside down
Students filmed Madden as he stood in front of the classroom and covered a pot of water with what appeared to be a thin piece of cardboard.
When she turned the jar over, an air bubble appeared at the top of the liquid and she slowly withdrew her hand, showing that the cardboard would not fall off.
Madden told her students that turning the jar over created air pressure that pushed up in all directions, creating a magnet-like effect between the cardboard and the water.
The air pressure would trap the liquid, she told her students as she removed the cardboard from the bottom.
When she turned the jar over, an air bubble appeared at the top of the liquid and she slowly removed her hand, showing that the cardboard would not fall off.
When no water fell from the jar, her students screamed in horror as she explained that the air pressure in the jar was stronger than the force of gravity holding it in the container.
Madden poked the exposed water and apart from a few drops, no water came out.
Her students ran to her desk to touch the water, exploding with excitement as the liquid remained firmly in the jar.
The video received heartwarming comments praising Madden’s educational efforts, with one person writing: ‘She looks so happy she’s making a core memory for these kids, and she’s teaching.
‘Many teachers don’t get time to teach, but his was beautiful to see.’
Another wrote: ‘This is how you put children on the right path. Satisfy their curiosity with simple but amazing things.
“I bet those kids will remember her for a long time in their lives.”
