This dinner hack is sure to be a crowd-pleaser. The next time you invite guests over for dinner, you can keep things like bread and other items warmer for longer by placing some aluminum foil underneath them. The foil will trap more heat and transfer it to the food better than a normal paper napkin. The best part is that you can place the foil underneath a fancy napkin to hide it and it still works.
Of course, if you just want to keep something warm for the longest amount of time possible and don't care about looks, you can completely wrap it in foil to trap heat.
