milk

If you soak the liver in milk for about 20 to 30 minutes before cooking, then rinse it thoroughly with water and pat it dry, the odor will be reduced remarkably and it will turn out delicious. However, since today’s liver generally has less of a smell than it used to, and some point out that soaking it in milk can leach out nutrients, it’s best to try this method only if you find the odor particularly bothersome.

nitrogen

Among the gases contained in human exhaled breath, the one with the highest proportion is nitrogen. About 78% of the air we inhale for breathing is made up of nitrogen. The nitrogen that enters the body is neither consumed nor absorbed through human respiratory activity. Therefore, nearly the same amount of nitrogen that is inhaled is expelled from the body as is, making it the most abundant component in exhaled breath.

3 cups

One tablespoon is defined as 15 ml, and one teaspoon is defined as 5 ml. Therefore, one tablespoon is equivalent to three teaspoons. These units often appear in cooking recipes, and remembering this 1-to-3 ratio is very handy.

Lake Tazawa

Lake Tazawa is a freshwater lake in Semboku City, Akita Prefecture, and is known as the deepest lake in Japan. Its maximum depth reaches 423.4 meters.

citric acid

Using citric acid in the final rinse of your laundry can make clothes fluffy and soft as a substitute for fabric softener. This is because many laundry detergents are alkaline, and adding acidic citric acid triggers a neutralization reaction that helps reduce stiffness in the fabric.

carbonated drink

When you want to remove tarnish or discoloration from silver accessories, using a carbonated drink can actually be effective. Carbonated beverages contain acidic components that loosen dirt and oxides on the surface of silver items, making them easy to remove. To use, soak the silver item in a carbonated drink for a few minutes, then gently polish it with a soft cloth. However, leaving it for too long can have the opposite effect, so keep the soaking time short. Also, if the item is decorated, take care not to damage the decorative parts.

1 to 2 hours before bedtime

The best time to take a bath is said to be 1 to 2 hours before bedtime. When a person’s core body temperature drops, it naturally induces sleepiness. After warming your body in the bath, your temperature gradually falls, which helps you fall asleep smoothly and is believed to promote higher-quality sleep. Because it also enhances relaxation, it’s recommended for people who have trouble falling asleep or who want more comfortable sleep to bathe during this time window.
