Awesome idea for a large summer cookout or at the beach with family. Put shucked corn in a cooler. Pour boiling water over corn then close the cooler. In about 30 minutes you have perfectly cooked corn.
Put pasta salad in jars with lids for an outdoor party/food gathering. - You could then fill large serving bowls from the dollar store with ice and set the jars inside to keep things fresh, but looking nice.
