Can the BlenderBottle be used to mix hot liquids?
No. Hot or warm liquids may build up pressure within the bottle and cause the flip cap to open unexpectedly and spray contents. Some ingredients such as pancake batter may also build up pressure within the bottle. When mixing these types of ingredients, you should hold your finger over the flip cap while shaking and use caution when opening the flip cap. Always point the spout away from face when opening the flip cap.
