I put chicken nuggets in the thermo, but why didn't the insulation last as long as the description said it would? When testing the thermo insulation, we typically use water. Yet, solid foods like chicken nuggets differ from water, affecting heat distribution and potentially reducing insulation duration. How long does this product hold heat? Hot water at 212°F is insulated to about 140°F after 5h and cold water at 24.8°F is insulated to about 60°F after 8h. Is this dishwasher or microwave safe? No, the sticker will peel in high temperature, soaking, etc. What if it's not as insulated as the description says? For better insulation, please preheat/pre-cool sufficiently before use. How old is this thermo for? For 5-7 year olds.
