Dear Customers，
As we received some of your feedback on the bottle, we have amended the instructions to provide you with a clearer understanding. Do follow the instructions below closely to see amazing results with your Thermos Bottle! Tested and true!

Instructions for Use:
First Cup

Put hot water into the 55°C Thermos Bottle， shake it up and down for 30 seconds to 1 minute and the water will be rapidly cooled to a warm， drinkable 55°C. It can also keep the drink warm for hours.

The bottle will turn warm as it has absorbed the heat from the first cup of hot water. Finish up the water or pour it out to proceed to the second cup.

Second Cup

Situation 1: To warm up cold water， pour cold water immediately into the Thermos Bottle， shake it up and down for 30 seconds to 1 minute and the heat from the first cup will be transferred to the cold water， which will become a warm 55°C.

Situation 2: To cool down another glass of hot water， pour hot water into the Thermos Bottle after about half an hour (to allow the stored heat to dissipate). Shake it up and down in the same way， and the hot water will be rapidly cooled to a drinkable 55°C.

Remember, the first cup always has to be hot water so the bottle can absorb the heat and transfer it to the second cup (cold water).
