In this tutorial, we will be conducting a hot and cold test on the Hydro Flask Food Jar to see how well it is able to retain the temperature of hot and cold foods.
Step 1: Preparation
First, you will need to gather all the necessary materials for the test. This includes the Hydro Flask Food Jar, a food item that you would like to test (such as hot soup or cold salad), a thermometer, and a timer.
Step 2: Preheating or pre-cooling the Food Jar
If you are testing a hot food item, preheat the Food Jar by filling it with boiling water and letting it sit for a few minutes. This will help to ensure that the Food Jar is at the optimal temperature to keep hot foods hot.
If you are testing a cold food item, you can pre-cool the Food Jar by placing it in the refrigerator for a few hours before conducting the test. This will help to ensure that the Food Jar is at the optimal temperature to keep cold foods cold.
Step 3: Testing the Food Jar with a hot food item
Once the Food Jar has been preheated, carefully pour the hot food item into the Food Jar, making sure to leave some space at the top for the lid to be sealed properly. Place the lid securely on the Food Jar.
Use a thermometer to take the initial temperature of the hot food item and record it. Start the timer and let the Food Jar sit for a predetermined amount of time (e.g. 4 hours) before checking the temperature again.
After the set amount of time has passed, open the Food Jar and use the thermometer to take the final temperature of the hot food item. Compare this temperature to the initial temperature to see how well the Food Jar was able to retain the heat.
Step 4: Testing the Food Jar with a cold food item
For testing a cold food item, follow the same steps as above but with a cold food item instead. Be sure to pre-cool the Food Jar before pouring in the cold food item.
Take the initial temperature of the cold food item, seal the Food Jar, and start the timer. After the set amount of time has passed, open the Food Jar and take the final temperature of the cold food item. Compare this temperature to the initial temperature to see how well the Food Jar was able to retain the cold temperature.
Step 5: Conclusion
Based on the results of the hot and cold test, you can determine how well the Hydro Flask Food Jar is able to retain the temperature of hot and cold foods. If the food item stayed at a consistent temperature throughout the test, then the Food Jar has proven to be effective in keeping hot foods hot and cold foods cold.
Overall, the Hydro Flask Food Jar is a reliable option for keeping your food at the desired temperature while on the go. Its durable construction and vacuum-insulated design make it a great choice for anyone looking to enjoy a hot or cold meal throughout the day.
I got these and if you pour boiling water in them first, then pour it out before putting in your food they do keep food warm for at least 5 hours.
i bought 20oz food jar last week.
i am so disappointed by hydroflask..
i should have watch this before i bought😢
This thing sucks. I bought one and does not keep food warm.
I still prefer the hydro flask for making overnight chia pudding where I can eat right out of the container and occasionally take it to the nearby park to eat breakfast there. Whenever I need the food cold for longer I compromise and move the contents to my Stanley which is harder to eat from but better for insulation.
The more air there is, the harder it is to open later.
Air is more volatile than water and other liquids in general
I can vouch for this. I was disappointed by HydroFLask. It was my first one and I usually buy Stanley but this one was discounted at REI. I work in the backcountry and need food warm/hot and not cold. Every single time by lunchtime, my food is cold. Won't buy Hydroflask again. Im sticking to Stanley/Thermos
Thank you. I was just about to buy one..
My kind of break down. The only way to truly know is exactly how you did it. Thanks for the testing between the different canisters.
Thank you for your video
This seems to be a promo
What I have been wondering is: Won't food get over cooked if it is left hot for too long?
We have found if you pre heat or pre cold treat the hydro flask, it works better and keeps food cold or hot longer. Agree with the Stanley though.
Thank you very informative
Good review. Good work keep it p
It’s says on the website it stays cold for 4 hours it’s meant for school lunches and areas bring it for quick packs
