How It Works
Anatomy of a Hot Poc
Hot Poc pouches are made to be enjoyed in the outdoors, which is why our current collection features the Hot Hand in different activities:
- Snowboarding
- Surfing
- Hiking
- Skiing
The pouch is safely made of PVC and can be in direct contact with the skin, whether or not the Hot Poc is activated.
Please avoid applying the activated Hot Poc directly on a baby’s skin, as they tend to be more sensitive to heat.
The liquid inside the Hot Poc is non-toxic and made of two ingredients: water and acetate sodium, which is a big scientific name for what we commonly call salt. In other words, the solution is simply a super-saturated mixture of salted water.
This simple, yet essential piece can be considered the heart of the Hot Poc. It is literally a floating piece of metal inside the pouch with one crucial role. When it is bent or “clicked”, its interaction with the liquid triggers the heat reaction for you to enjoy.
The Science Behind The Heat
Let’s take a stroll down memory lane, all the way back to your high school chemistry class.
1. The Key Ingredient
2. From Crystal Clear to Opaque
When the metal disc is “clicked” or bent, microscopic pieces of metal are released, which creates “nucleation sites”. When in contact with these sites, the liquid changes from liquid to solid, a process called crystallization.
