Bottle with own lungs..!
To address the topic about the respiratory system, I propose this curious scientific experiment.
Only the following materials are required..!
An empty plastic bottle.
Some balloons.
A few straws.
A pair of latex gloves.
First, cut the bottle in half and place the latex glove by coating the bottom, simulating the diaphragm.
Then form a “Y” with the straws and hang the balloons from the ends.
Finally, introduce the entire structure into the bottle, children will be able to see with their own eyes how the lungs fill with air when the diaphragm expands and vice versa.
I leave you here an explanatory video..!
