What technologies are there that sound incredible but are real?

"Cooked eggs turn into raw eggs": This technology is not "turning cooked eggs back into raw eggs" in the usual sense, and it cannot achieve 100% recovery by "turning cooked eggs back into raw eggs". This technology uses a chemical substance to liquefy the protein of boiled eggs, and then cuts off the tightly wound protein molecular chains, so that they can be reconstructed and "reduced" into raw eggs. The liquid form of the egg has recovered from the solidified form, but its properties have changed, and this raw egg can no longer have the ability to hatch chickens. Its real significance is to make protein, which is denatured, inactivated and structurally disordered, regain its activity and fold back to its normal structure.

Boiled eggs become raw? This is just a metaphor.

"Control the weather": it is not the idealized ability of "changing the weather at will, raining whenever you want, and blowing whenever you want" in the traditional sense. The "weather control" mentioned in the answer actually refers to "preventing rain in a certain area on a certain day and ensuring the sunny state of the area on that day." Through artificial means, the weather state that should have rained in a certain area on a certain day has become a sunny weather state.

Methods: Plan to track and record the formation information of the cloud, and launch silver iodide rain bombs into the cloud a few days before the "demand day" to provide condensation nuclei for water vapor in the air and produce artificial rainfall; Or when the rain clouds move, artificially increase the rainfall in the upper reaches of the "battleground" and consume energy in advance. Finally, the artificial rain suppression of the required land was formed.

Point: it can't change all weather conditions; The scale of rainfall that can be stopped is limited; The sunny weather on the day of the military parade is natural and has not been artificially controlled (excluding the air quality on that day).
