Hunters and Construction workers Use these nifty objects throughout the winter months to keep warm in cold weather.   What is the science behind these handy items...
...This "hand warmer" heat pack contains a super saturated solution of water and sodium acetate. Snapping the metal disc creates chain reaction causing the solution to crystallize. The crystallization process gives off heat. The heat packs can be recharged back to the liquid state by boiling water for 10-15 minutes and allow it to slowly cool.  Reusable over and over again.  Comes with Teachers Guide.  

Also great therapy for strained muscles. Replaces electric heating pads.


Also available in a smaller size 4x4  with a Teachers Guide.
