I would like to post ideas, inventions, and ingenuity that are useful in everyday life.
The first is a simple thing to put water in a
plastic bottle, freeze it, apply the wind to the ice, and let the cold w
ind out again. https://www.youtube.com/watch?v=sH9y-amarTohttps://www.youtube.com/watch?v=x
-nYeetYvNo It’s hard to see in the video (it was the first video posted at the time of shoo
ting, and it has four blower fans and four AA batteries on the right side. The wind from the fan is put in the put bot
tle, it cools with ice, and the cold air is put out again. The white part is a pip
e that is thrust into the pet bottle entrance and the f
rame that secures the battery and fan is made by a 3D printer.
As a feature, instead of applying the wind from “outside the plastic bott
le”, put the wind in the “plastic bottle” and put it out again. When I s
ay what is good, when I apply the wind from outside the plastic bottle, it condenses and water drips, but if it is in a plastic bottle, there is no condensation.
