A one-half scale model of a pump made of transparent material is placed on the floor, and when the handle is moved up and down, water can actually be pumped out of the water tank at the bottom.
As you do so, you can see how the two valves inside the pump work.

"That's right. Take, for example, a mixture of water and ethanol. The boiling point of water is 100 degrees Celsius, and ethanol is ......."
It's about 78.4 degrees, father.

Since Jin did not immediately come up with the boiling point of ethanol, the old man and Reiko quickly followed up.

As you heard, the boiling point of ethanol is 78.4 degrees Celsius, which is quite close to the boiling point of water. Therefore, it would take a lot of time and effort to separate only ethanol from a mixture of water and ethanol.
"I see, that's true."

The most familiar mixture of water and ethanol is sake.
Freshly brewed sake contains a lot of water, so it is sometimes distilled to raise the alcohol (ethanol) content (and also to eliminate impurities), but pure ethanol cannot be separated in this process.
In fact, it is not possible to distill alcohol (spiritus) with an ethanol content of more than 96%.

To get 100 percent ethanol from this, you have to do something other than distillation.
