Preparations are underway in Louisiana for Hurricane Francine and sadly some are leaving their home behind to escape the path of the storm.

While away from your home in southern Louisiana you may lose electricity, which means you could lose what is left behind in the freezer or refrigerator.

A few years ago Sheila Russell shared this tip on Facebook and it lives on. She notes that if you are expecting to lose power, you should place a quarter or any type of coin on top of a frozen cup of water in your freezer.

The reason for placing a coin on a frozen cup of water is that when you return home if you find the quarter has moved towards the bottom of the cup it's a sign you lost power and the contents in your freezer may be contaminated.

This "trick" can tell you whether or not your food is safe to eat or if it's not safe to eat and should be disposed of.

I know a lot of people with camps or second homes that do this and you should consider doing this too if you are expecting the hurricane to impact your area.

Hurricane Francine is expected to make landfall in southeastern Louisiana as a strong Category 1 or weak Category 2 story, thus this one simple "hack" could be a good indicator when you return.

Landfall is expected late Wednesday afternoon, into early evening and the possibility of losing power as the storm sweeps across the area is an issue.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
