FIDGET ICE PACKS

Following are specifications of different gel types.

	Blue Gel	Green gel	Pink Gel
Cooling agent	Nontoxic superabsorbent polymer (SAP) which turns water into a chunky gel, forming a special frozen ice core	Food thickener methyl cellulose (MC) dissolved in small amount of food-grade glycerin, and lowers freezing point of water	A 3:1 mixture of SAP and MC, providing advantages from both Blue Gel and Green Gel
How to freeze	Best frozen with deep grooves facing upward	Best frozen with deep grooves facing upward	Best frozen with deep grooves facing upward
Expected ice core	When repeatedly refrozen, a solid ice core leaves air gaps under shell which is filled by melted gel while in use, for consistent groove temperature, and satisfactory thumps when shaken	When frozen, a mushy ice core hugs inner surfaces of shell leaving no air gaps, thus provides maximum cooling on groove surfaces when first removed from freezer	A solid ice core like Blue Gel with satisfactory thumps when shaken, but without air gaps thus the initial cold shock like Green Gel
Bulging behavior	Susceptible to slight bulging in the designated bulging area (the wavy insulating ridges), if the ice pack is frozen upright. Instead, freeze the pack with deep grooves facing upward.	Much less susceptible to bulging compared to Blue Gel	Slightly less susceptible to bulging compared to Blue Gel
Best for	Treating sore fingertips to forestall blister formations	Providing initial cold shock for fast but shorter cooling	Initial cold shock like Green Gel, and lasts almost as long as Blue Gel
