8 Old-Fashioned Life Hacks That Still Work Great Today

5. Check Your Batteries

To find out whether or not batteries are still good, try out this trick. Hold the battery about one to two centimeters in the air, then drop it on to a flat, hard surface. If the battery bounces and lands on its side, it’s no longer good. If it lands upright, it’s still good.

6. The Knuckle Trick

If you’re wondering how many days are in each month, refer to this trick. Each knuckle and coinciding “valley” on your hands represents a month. The knuckles are months with 31 days, and the valleys are months with 30 days (or less, in February’s case).

7. Spelling Tip

Let’s face it — spelling isn’t always easy! To simplify things a bit, remember this saying: “I before E, except after C.” It will help you when spelling words with i and e, since it can be difficult to remember which letter comes first.

8. Disinfect The Proper Way

To get the most life out of your sponge as possible (or anything else made of fabric), simply dump it in a pot of boiling water for about 10 minutes. It will be disinfected after that.
