Self Heating Bento Boxes!!

4 years ago

This is just amazing! I cant believe something like this even exists! You pull the string, that rips a bag full of water, and the water goes into these stones, and it creates a reaction (not sure exactly what the stones are, its something scientific) and the stones release heat which heats up the bento meal, how cool is that? I watched a programme called Cool Japan, its on sky (cabel) on a japanese channel, and i could believe how cool this is :) wish we had it here! Oh forgot to mention you can only get these at train stations! (in japan)
