It's amazing. We all know that the sound of inhaling hydrogen becomes thinner. What will it be like to inhale sulfur hexafluoride? Of course, it's rude~~Is it tender after being burnt by thunder? What do you think, little partner?

Now, the technicians from Philips, a sulfur hexafluoride gas manufacturer produced and operated by * * *, will tell you how to extinguish the candle!

The reason why sulfur hexafluoride gas extinguishes the candle is that the gas is 5-6 times heavier than air. When gas is poured from above, the air will be pushed away. Candles need oxygen to burn, and in the absence of oxygen, candles will go out. In addition, sulfur hexafluoride is inert and incombustible. Therefore, when sulfur hexafluoride gas is poured into the candle from above, the candle will be extinguished due to lack of oxygen.

Why can the tin foil boat be suspended above the sulfur hexafluoride gas? Here's how it works: sulfur hexafluoride is heavier than air, and its density is about five times that of air. It will deposit at the bottom of the fish tank, expel the air, and light objects will be suspended on it.

Come and expose the third little secret of sulfur hexafluoride! When sulfur hexafluoride gas is inhaled, sulfur hexafluoride will fill around the vocal cords. When we make a sound and the vocal cords vibrate, it is sulfur hexafluoride that is not the air we usually speak that is driven to vibrate. Because the molecular weight of sulfur hexafluoride is larger than the average molecular weight of air, and the vibration frequency is lower than that of air, there will be a deeper sound than usual.

You may ask: can other gases with higher molecular weight than air achieve this effect? The answer is yes, and different densities of gas will produce different sound changing effects! However, the premise is that high-purity sulfur hexafluoride is non-toxic, and many magic gases with large molecular weight are toxic. Don't try to use other gases to change your voice!
