In this article, we'll find out what causes rip currents, how you can recognize them and what you should do if one takes you out to sea. A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. These currents may extend 200 to 2,500 feet (61 to 762 m) lengthwise, but they are typically less than 30 feet (9 m) wide. Rip currents can move at a pretty good speed, often 5 miles per hour (8 kph) or faster.

Turns out the temperature at which food freezes and the freezer temperature it should be stored at can be two different things. Even if your freezer seems to be doing its job, you should know the correct temperature to set it to! Kitchen Fact: The ideal temperature range for your freezer is 0Â° Fahrenheit or below (-18Â° Celsius or below). Food stored at 0Â° Fahrenheit or below is safe to eat indefinitely (although quality and taste may be compromised after a while). While many foods will freeze at about 32Â° Fahrenheit, they need to be stored at 0Â° Fahrenheit to slow down deterioration, so colder is better. And don't worry about freezer burn with really cold temperatures â it's caused by exposure to air, not temperature.
