how it works

 

You may be wondering what’s going on inside the can - it’s quite simple and perfectly safe!

Inside is a can of food surrounded by an outer can and in the space between the two cans is a water sachet and processed granular limestone (the same basic compound found in some toothpastes).





When you insert the spike into the three holes in the top rim of the can this pierces the water sachet, the water then flows into the limestone and a natural reaction occurs between the limestone and water which produces heat. This warms up the food inside the can and within 8-12 minutes it will be a perfect eating temperature of 60-70°C
