New York teacher stuns students with truly gravity-defying experiment - can YOU work out how she did it?
A teacher has amazed her students by defying the laws of gravity.
Mrs. Madden, from Mount Kisco, New York, performed a spell bounding experiment for her science class by flipping a jar of water upside down in a way that not a drop spilled out from the opening.
While the feat appeared to be something of magic, it was possible using air pressure that flowed into the container and trapped the water inside.
A teacher from Mount Kisco, New York taught her young students how water could defy gravity and stay in a jar, even after it was flipped upside down
Students filmed Madden standing in front of the classroom and covering a jar of water with what seemed 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 removed her hand, showing the cardboard wouldn't fall off.
Madden told her students that by flipping the jar, it created air pressure which pushed upwards in all directions, causing a magnet-like effect between the cardboard and the water.
The air pressure would hold the liquid in, she told her students as she removed the cardboard from the bottom.

When no water fell from the jar, her students cried out in shock as she explained that the jar's air pressure was stronger than gravity which kept it in the container.
Madden poked the exposed water and aside from a few droplets, no water came out.
Her students rushed to her desk to touch the water, exploding with excitement as the liquid stayed firmly in its jar.
The video was captured in 2019, but has resurfaced on social media where it received heartwarming responses praising Madden's teaching efforts.
One person commented: 'She looks so happy that she is making a core memory for these kids, and she’s TEACHING.
'A lot of teachers don’t get time to teach but his was beautiful to watch.'
Another person wrote: 'This is how you put kids on the right path. Indulge their curiosity with simple but amazing stuff.
'I bet those kids will remember her well into their lives.'
