1, put the plastic bottle with hot water in the quilt.

First, collect some of our plastic beverage bottles. After washing, we poured hot water into it. Remember that the temperature of water should not be too high, otherwise the plastic will be easily deformed. After pouring hot water, tighten the bottle cap and put it under the bed. After 5 to 7 minutes, we can take out the bottle and get into bed. Then you will find that the bed is still very warm.
