Before the telephone and satellite communication was invented, Morse code was used to transmit messages over long distances quickly. For example, ships often used Morse code to send distress signals. Additionally, in the past, if you wanted to tell your family when your train would arrive at the station, you could send them a letter in Morse code.

What’s Morse code?
Morse code was invented by Samuel Morse and is a means of communication that uses long and short signals to transmit messages. Morse code is often sent using sound or light signals. It can also be written. For example, short signals are represented as dots and long signals as dashes:

• A =
• E =
• R =
• T =

Therefore, to communicate the letter A in Morse code, you must transmit a short sound followed by a long sound. Each letter of the alphabet has its own code, so you can easily spell words and phrases using the right combination of signals.

It’s a bit complicated, isn’t it? Fortunately, today you can simply text, email, or phone your friends. However, the Morse code is still used in military emergencies.

Have you ever inhaled helium from a balloon? If so, you may have noticed that your voice becomes higher than usual. This is a funny and intriguing side effect. Here’s why it happens.

Your vocal cords vibrate when you speak or sing, much like the strings on a guitar. How fast the air passes through your vocal cords determines the pitch of your voice. Slow-moving air makes low-pitched sounds, while fast-moving air makes high-pitched sounds.

Helium is lighter than air. Therefore, when you inhale helium, it travels much more quickly across your vocal cords than oxygen, making your voice sound higher than normal.

Be careful
Though it’s fun to alter the pitch of your voice by inhaling helium, don’t overdo it. If you inhale too much, you could deprive your body of oxygen and faint. It’s perfectly safe to inhale small quantities of helium, but doing so repeatedly can have dangerous consequences.

1. Elephants can’t jump because they’re too heavy. Their bones would break on landing.

2. Elephant trunks are very flexible and contain up to 150,000 muscles. This essential appendage functions as a nose and arm. Elephants use their trunks to communicate, clean themselves, and gather food. However, elephants don’t eat through their trunks.

3. Elephants spend around 16 hours a day eating. They can eat more than 440 pounds of plants and drink over 26 gallons of water a day.

4. Although elephant skin is thick, it’s also very sensitive. In fact, an elephant can feel a small insect land on its back. Additionally, elephants cover their skin with mud to stay cool in the hot sun.

5. An elephant’s powerful trumpet-like call can be heard up to five miles away.

6. Contrary to popular belief, elephants aren’t afraid of mice. However, they fear ants and bees that can crawl into their trunks.

7. Elephants can swim several miles at a time. Additionally, they use their trunks as snorkels to breathe underwater.

8. Elephant feet are very sensitive and can feel ground vibrations more than six miles away.

9. Female elephants carry their young for 20 to 22 months before giving birth. That’s almost two years!
