Hot water treasure / Hot water treasure

Hot water treasure adopted high temperature thermal conductive materials in this surface, internal is aluminum and copper oxide，erects lots of quality of heat after pulled the rope start the reaction.The chemical reaction is：
2Al+Fe2O3=Al2O3+2Fe （let out a lot of heat )
By using this device peoples can quickly heating a small amount of water ,simplify the cumbersome process of heating water and drink hot water even play outside
