As we probably all remember from our school days, cold travels down and heat moves upwards. On that basis, with science in mind, you'd be best off with a layer of gel packs across the top of your contents so they continue to radiate cold down towards your food and drink.
Put them at the bottom of the cooler, ice or ice packs on top of that, warmer but still cool items on top. If you need it REALLY frozen, sub dry-ice for wet ice.
Heat rises, cold travels down... ice should be on the top for best cooling. Buy dry ice, lasts long time for food and regular ice for drinks cooler. Drinks in water as ice melts will be nice and cold.
Dr. Alex Tauberg, a certified sports chiropractor in Pittsburgh, recommends putting the ice either over the pain or at the base of your skull. Always keep a cloth between your skin and the ice pack, and press firmly against all the curves of the affected area.
Icing an injury typically takes place immediately after the injury occurs. Using a cold compress or ice pack on a strained muscle can decrease inflammation and numb pain in the area. Icing is effective at reducing pain and swelling because the cold constricts blood vessels and decreases circulation to the area.
Your icebox will perform at its best if you cool down the contents to go inside first. Place your food items in a fridge for a few hours first, then put the cold contents into the icebox. This way, you're saving your ice from having to cool the contents down, which in turn means the ice lasts longer.

Cool off
You can cool yourself or a child safely with a few home remedies: Apply a cold pack under your arm for up to 10 minutes at a time. Don't use cold packs on babies or young children, though. They can't always tell you if it's too cold for their skin.
When an injury or inflammation (such as tendonitis or bursitis) occurs, tissues are damaged. Cold numbs the affected area, which can reduce pain and tenderness. Cold can also reduce swelling and inflammation.
It is recommended to have dry ice at the bottom and top of your perishables, whether frozen food or the fruits of a hunting expedition. Due to its extremely low temperature, dry ice will freeze the food it comes into direct contact with. This will ensure your perishables stay frozen without thawing.
The ice packs are always put on top of the foods in the cooler. Putting the ice packs on top will ensure all the foods you put in the cooler bag remain cold. The cool air will go down while the warm air rises, thus making all the foods in the cooler remain cold.
Block ice will melt slower and keep your cooler cold for longer. Cubed ice will wrap around all those beverages, keeping every can or bottle cold. Place blocks of ice along the bottom of the cooler first. If you can't find blocks of ice, you can make your own by freezing a large container of water.
Layer items with ice packs or bags of ice. Start with a layer of ice packs or ice on top of the insulation. Place drinks and items you'll use frequently on top of this layer. Add another layer of ice packs or ice, and then put in perishable items like fruits, vegetables, dairy products, and meats.
When you use an ice pack, pay attention to how your skin feels. The first stage of ice burn is known as frostnip. Frostnip causes your skin to get red or pale with a tingling and prickly sensation. It's a sign that you should remove the ice pack and warm the area so you don't damage your skin.
Place ice bags over as much of the body as you can. Ice packs against the neck, under the arms, and in the groin area, where large blood vessels lie close to the skin surface, will help quickly cool down a victim of heatstroke.
Always keep a cloth between your skin and the ice pack, and press firmly against all the curves of the affected area. Do not apply ice for longer than 15 to 20 minutes at a time, and do not fall asleep with the ice on your skin. Commercial cold packs are too heavy and bulky for use on or around the eye.
Definition. ICE stands for Initial, Change, Equilibrium. It's a method used to solve equilibrium problems by organizing data into an ICE table to calculate concentrations at equilibrium. congrats on reading the definition of ICE Box Methodology.
So, you might ask, if denser water sinks, why does the ice form on top? Quirk alert: As water approaches its freezing point (32 degrees F / 0 degrees C) it becomes less dense than the water around it and rises to the top of the surrounding water.
Identify the inner bag of liquid and squeeze it as hard as you can to release its contents and begin the reaction. Shake the cold pack to quicken the reaction; the pack should become cold within a few seconds. Wrap the cold pack in a gel pack cover or a towel to prevent direct contact with the skin.
Before the invention of refrigerators, an ice box was how food was kept cold. An ice box was usually made of wood and lined with metal, usually tin or zinc. The hollow walls were packed with insulation, such as straw, sawdust, cork, or seaweed. A large block of ice was placed in a compartment in the top of the icebox.
One way is to simply add salt to the water before freezing it. The salt will lower the freezing point, causing the ice to melt slower and keeping your drinks colder for longer. You can also use salt to melt ice that has already formed. Simply sprinkle salt on top of the ice and watch as it melts.
