When desiring to utilize the canned food, initiate the process by first opening the lid of the chemical compartment. Proceed by pouring water into this section, thereby triggering a reaction involving magnesium, calcium oxide, and water. This reaction rapidly elevates the temperature within the food container to an efficient 90 degrees Celsius. This thermal transformation takes approximately seven minutes. Subsequently, the food container can be opened, revealing the perfectly heated contents.
