staying warm in a tube this time of year?

[BADFISH]

THE ORIGINAL WARMERS NEEDED AIR TO REACT AND PRODUCE HEAT...THE NEW "TECHNOLOGY" IS THAT THEY DONT NEED AIR ANYMORE...HENCE YOU DONT HAVE TO SHAKE EM TO MIX WITH AIR...YOU JUST OPEN EM UP GIVE A RATTLE OR TWO AND STICK EM WHERE THE SUN DONT WARM...ANY PLACE YOU WANT EM. THEY ARE BETTER THAN THE OLD ONES, WHICH IF NO AIR WAS AROUND THEY WENT COLD....THE NEW KIND GO FOREVER. I PUT EM IN MY POCKETS HIKING IN THE WINTER...TO FIND A X-MAS TREE, AND THEY ARE WARM TILL WAAAAAYY AFTER I GET HOME AND AM TRYING TO STUFF THE GRISWOLD TREE INTO MY LIVING ROOM.LOL

LATERS,
