Why can't the water flows down the bottle?
Why did the water drip and bubbles escape to the top, when you shake it a little?
Swirl the bottle creating a hurricane and a vortex is formed where water gushed downward.
En tried swirling the bottle and also shake it in a horizontal position.
At the end of experiment, she said "the speed of water flowingis faster when there is little water left"
