Chapter 259: A Novel Assistance Package
At noon, Su Bai silently performed his Daily Check In and opened his Assistance Package, receiving a 55 degrees thermal flask.
When he woke up in the morning, because the fox eared girl was always around, he had forgotten to check in.
He stared at the black cup in his hand, surprised that such a cup existed.
“Well, it’s actually quite useful in the hot summer…” Su Bai opened the cup and poured some hot water in.
After screwing on the lid, he started shaking it. After a few minutes, he stopped.
Su Bai opened the lid and took a gentle sip, raising his eyebrows. “Not bad, it really turned into lukewarm water.”
The 55 degrees thermal flask was a new product from Earth, where one could pour in boiling water and shake it to get water at 55 degrees. It was quite novel. The main working principle behind it was the micron-level material for heat transfer stored in the food-grade stainless steel interlayer.
These materials would undergo a reversible solid-liquid transformation at the micron level as the temperature changed.
When the water temperature was above 55°C, it could quickly absorb and store the heat. Thus, bringing the water temperature down to around 55°C. When the water temperature fell below 55°C, the material would slowly release heat instead.
