"Everyone turn your textbooks to page 78, the chapter on metals and their compounds."
"We previously did an experiment with electrolysis of water to produce hydrogen, and today we'll produce hydrogen through another method—iron reacting with water vapor."
Lin Li looked at Bai Bufan, and Bai Bufan looked at Lin Li.
"I'll never forget your world-shattering wisdom," Lin Li chuckled.
Bai Bufan had proposed a suggestion during that experiment class.
—— "Since electrolysis of water gives us hydrogen and oxygen, and drowning happens due to a lack of oxygen, why not, in the future when someone is drowning, pass a high-voltage current through the water. Electrolyze a large volume of water to produce a lot of oxygen, providing it to the drowning person to breathe."
"That's enough," Bai Bufan sweated like a little yellow bean, "Lin Li, you're no angel either."
After hearing Bai Bufan's proposal, Lin Li built upon it.
