The 10 Pound Ice Pack Ice Alternative
We have learned a lot about coolers and how to keep 'stuff' cold using ice and ice packs. At first, we were testing our product against an equal amount of bagged ice - 10#. The Ri beat out a ten pound bag of ice in every way, every time. So we knew it worked better and that was based on simple science. Remember the basic law of heat transfer: Hot to Cold. Cold Objects absorb heat from warmer objects, period. When that happens, it is transferred in one or more of three ways: Conduction, Convection, and Radiation.
Responsible Ice™ technically is a cooler and heat sink. Simply put, a 'heat sink' absorbs heat, and that is one of the ways the Ri works!
Regular bagged ice generally works by the first method of heat transfer- Conduction. When you put a bag of ice in a cooler on top of drinks, it immediately starts melting, creating a ice/water bath. This direct contact of the ice/water with the drinks is 'conduction' and that heat transfer will continue until both objects are the same temperature.
The Ri not only can 'conduct' it's cold, it uses the other two methods of Heat Transfer. Convection and Radiation. Convection is the movement of gases and liquid based on a heat differential. Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks. A Solid Frozen Ri is as low as 0° when you place it in the cooler. When you close the lid, it creates a enclosed environment that allows the Ri to circulate ice cold air throughout the cooler. In addition, the Ri will passively circulate ICE COLD air because of it's patent pending design.
Because the Ri is creating ice cold air and moving it, it has to change places with the 'warmer' air in environment. This circulating cold air keeps all of the items in the cooler the same, cold temperature. As you know, regular ice really only cools (and drenches) what it touches. So the coldest items in the coolers are the ones in the water. Better hope it's not your sandwiches ;-/ In a cooler with bagged ice in it, you will see condensation. We learned in school, that condensation only builds up on cold surfaces in warmer air. That means that there is warm air in that cooler with bagged ice! Ugh. In a cooler with the Ri, NO CONDENSATION.
The Ri also utilizes the third Heat Transfer Process- Radiation. Let me explain: When you stand 10' away from a fire place you feel warm heat that is radiated heat through electromagnetic waves reaching your body. Because your body is cooler, it absorbs the heat. It's simple science. Well, Radiation works in your cooler too. Remember the basic law of heat transfer- Hot to Cold. When we place a Solid Frozen, 0° Ri in the cooler with objects that are warmer, the science takes over. The heat of the object placed into the cooler with the Ice Cold Ri will continually drop [releasing it's heat] until the two objects are the same temperature. In an inexpensive cooler...about 24 hours, in a good cooler- many days.
Coolers- Insulation and Seal.
Because those natural, scientific principles are constantly working, creating that optimal environment is so important. We have tested countless coolers and have concluded that maintaining that sealed atmosphere makes ice or ice packs work longer.
LifeTime Coolers: We have done extensive testing with this manufacturers' 28 and 55 QT coolers. May 2020-, we just finished a 4 day test with the 55 QT- that video is on You tube at : https://youtu.be/DptYBD35M8M. There is also a video review of the 28 Qt on the channel too.
It is an amazing cooler, the price makes it even more amazing. nuff said, it's a good cooler. This 55 QT cooler is my personal cooler.
You may remember in science and math of how exponential processes work. In a nutshell- two 5 pound Ice packs equal a certain amount of 'cooling power', but it does not equal the 'cooling power' of one ten pound ice pack. Currently there are several companies that manufacture large ice packs. They all use chemicals, not science to get their ice packs to freeze at lower temperatures. We don't use chemicals, PERIOD.
Anyway if you got this far, we're gonna be friends! ;-/ please take a look at our Facebook Page https://www.facebook.com/responsibleice/ We like to do Daily Updates and report new info and uses for this cool new tool there and on our Instagram page. Stay Safe out there and adventure on!

Here is a short time-lapse of the Ri freezing over 14 hours. The Ri is made out of a special HDPE Plastic which has the ability to stretch up to 600%. Plain water permanently sealed inside tries to expand while the Ri holds in that pressure, creating really, really COLD Ice.
