A man tries to heat up his leftover food with a blow drier. Not having a microwave oven and watching a video of a college student heating food with blow dryer, he decides do it himself. He did this to see if it works or not. After one minute of blow drying there was no effect on the food.
After three minutes the broth in the food became somewhere near to the room temperature, but it was still not eatable. After five minute it started to work and the food became near to state where it could be kept in throat.
After whole ten minutes the food was nearly heated. And it was all ready to be eaten. This rather careless experiment showed that a blow drier can be used to heat your food, but it surely isn’t a better way than a using a microwave oven or a stove.
