1. M&Ms are the most-loved candy... in space. Seriously. M&Ms have become part of the standard menu for astronauts aboard the International Space Station. Why are they the perfect snack? They're bite-sized and aren't likely to crumble - plus, astronauts love using them to explain science concepts to students in educational videos. Check it out.

2. Mary Jane candies stick to their roots. The design of the Mary Jane candies - a yellow wrapper with a red stripe and drawing of a young girl, has stayed the same for over 100 years and the recipe of peanut butter and molasses has stayed the same, too. The chews are named after creator, Charles H. Miller's beloved aunt and were sold in Miller's Boston home that turned into a candy shop - the same home that Paul Revere once lived in. Fast forward more than 200 years, Miller's candy company was sold to NECCO, where they produce Mary Janes in Revere, Massachusetts.

3. Naming the Snickers bar was not a laughing matter. The founder of Mars, Inc., Frank Mars, invented the Snickers bar in 1930. He named it after his favorite race horse, Snickers, that had passed away. Snickers was raised on his family's farm, the Milky Way, in Tennessee. 

4. Reese's Peanut Butter Cups are the brainchild of a former Hershey employee. Harry Burnett Reese started milking cows at one of Hershey Chocolate Company's dairy farms, but when his facility shut down, he was out of a job. He opened his own company, but didn't have any luck and ended up back at Hershey, this time in the shipping department. He decided to try candy making again and incorporated his new venture, H.B. Reese Candy Company. Five years later, in 1928, the Peanut Butter Cup was introduced and the rest is history. Reese's company ended up where it essentially started - Harry passed away in 1956 and Hershey acquired  H.B. Reese Candy Company in 1963. Reese's Peanut Butter Cups went on to become Hershey's bestselling offering.

5. Skittles...good for you and good for cows? A pack of Skittles contains a decent percentage of your daily recommended amount of Vitamin C. After hundreds of thousands of Skittles were discovered on a motorway in Wisconsin after falling out of a truck, the investigation concluded that Mars sells unused ingredients to clients who then mix them with other materials to make animal feed. Cattle nutritionists say Skittles are broken down mixed with other ingredients to achieve the correct nutritional profile for cattle feed.  Check out the full story .
