This experiment proves that Ai can find water?

You also need: a cigarette with the same structure as the moxa stick (a paper roll filled with tobacco), and a paper roll without any material.

Only in this way can we clearly distinguish whether Ai is looking for water or tobacco leaves are looking for water or all cigarettes are looking for water.

It should be noted that the same fire location, the same water temperature, the same thickness and length, the same size of the ignited fire, to avoid the interference of external airflow, everyone should leave more than five meters, have a high-speed camera, and the transparency of the cup should be the same. If the transparency of the plastic cup is not estimated enough, it is best to change the glass. It is best to process the smoke into a high contrast color.

Moxibustion is a long cylindrical roll made of moxa wrapped in cotton paper, which is mainly used for moxibustion. Moxibustion is one of the oldest medical technologies in China, which belongs to the external treatment of traditional Chinese medicine. It can warm channels and dispel cold, promote qi and blood circulation, dispel cold and remove dampness. It is suitable for arthralgia due to wind-cold-dampness, muscle numbness, joint and limb pain, and cervical spondylosis.

Identification of moxa sticks

One. Look at the color of the moxa stick: a good moxa stick is khaki, with a very small amount of green and black stalks and fine particles. Inferior moxa is cyan and blue-black, and the stalks are much larger.

Two. Smell the smell of moxa sticks: good quality moxa sticks smell fragrant and light, not pungent, poor quality moxa sticks smell strong and pungent, and worse moxa sticks smell musty.

Three. Touch the texture of moxa: Good moxa feels soft and delicate, while poor moxa feels rough. Good moxa is easy to hold together, and even if the wrapping paper is torn off, it will not be completely scattered. And poor Ai, the wrapping paper fell apart as soon as it was torn. Figure 1 is the comparison of wormwood at 5: 1, 10: 1, 30: 1. Everyone knows the quality of wormwood at a glance.

Four. Feel the heat of the moxa stick: a good moxa stick has a soft heat and strong penetration. Inferior moxa sticks have strong firepower, weak penetration and are easy to burn.

Five. Look at the burning speed: because the moxa with high proportion is delicate and fluffy, the moxa with low proportion has much less impurities, so the moxa with high proportion burns faster than the moxa with low proportion.

This is often misunderstood by many people, who think that this kind of moxa stick burns too fast and is not durable. As we all know, the effect of flame-resistant moxa sticks is much worse than that of flame-resistant moxa sticks. Isn't the purpose of moxibustion to achieve the effect of treating diseases and preserving health? Just like a cotton ball, a cotton ball mixed with stones and sand. When they burn together, they must be pure cotton balls that burn quickly.

Six. Look at the ashes after burning moxa sticks: the ashes after burning moxa sticks with good quality are gray, delicate and smooth to the touch, and difficult to scatter, while the ashes after burning moxa sticks with poor quality are dark gray, scattered everywhere and rough and granular to the touch.
