How to silently fart in workplace?
Do not let it build up, so that you are able pass an emission of gas from your posterior without making a noise. The longer you hold it in, the greater the chances are that your fart will be audible.
Another trick to help out, would be to avoid eating too much food that give you gas.
Foods That Can Cause Gas
Carbohydrate-rich foods tend to cause gas, whereas foods that contain mostly fats and proteins do not. That doesn't mean carbs are bad for you—in fact, lots of healthy carb-rich foods are high in beneficial nutrients like fiber.
That said, if you suddenly add more fruits and vegetables to your diet, you might notice more gas. The exchange may not seem fair since by adding these healthy whole foods, you're actually improving your diet. But take heart: Not all plant foods cause gas in everyone. Often, as your body adjusts to the change, you'll notice less gas.
With a little trial and error, you can also determine which foods you are most sensitive to. Commonly, these include:
Beans such as navy beans, chickpeas, pinto beans, and white beans
Vegetables including asparagus, broccoli, Brussels sprouts, cabbage, onions, and mushrooms
Fruits such as apples, peaches, and pears
Starches including potatoes, corn, pasta, and wheat, and any foods made with these ingredients
Sugar-sweetened drinks and apple juice
Carbonated beverages such as soda and beer
Dairy products such as milk, cream, and ice cream
Sugar alcohols such as sorbitol, mannitol, and xylitol
The common denominator here is carbohydrates that contain fructose, lactose, insoluble fiber, and starch. These ferment in the large intestine, releasing gas as they do.
