Outdoor parties in the summer promise tons of fun, but those warm temperatures also wreak havoc on the ice you have on hand. An extra freezer offers a great option, but it's an option not a lot of people have. Many people opt to use coolers to keep ice outside for a party. Go with light colors, since they absorb less heat and can slow down melting. You should also avoid putting your cooler in direct sunlight. Try lining a cooler with aluminum foil, or even putting bubble wrap under the foil for more insulation. Once you fill a cooler with your bags of ice, cover with a blanket.
