Kinder spielen gerne mit Seifenblasenmaschinen. Blasen steigen zuerst auf und fallen dann. Was ist das Prinzip?
Jul 10, 2022
Now many young people blow bubbles with bubble machines. The bubbles blown by the bubble machine are not only of appropriate size, but also can be connected in series sometimes, which looks very good. Although the bubble liquid used in the bubble machine is distributed by the manufacturer, it cannot be changed. The composition of this foam liquid must be the same as the foam water we played with when we were young. So blowing bubbles with a bubble machine is basically a way of playing, but now it is more gorgeous than when we used to blow bubbles with a pen holder when we were young.
Bubbles are actually due to the surface tension of water. Water molecules between liquids will be pulled by water and air. Because the traction between water molecules is greater than that between water and air, water molecules will stick together in the air, that is, bubbles. We learned the principle of bubbles flying out of the bubble machine in high school physics. We should all know that foam are formed by wind. After bubbles form and fly out, the wind will not shift, so the bubbles just flying out of the bubble machine will drift upward for a distance with the wind. After the wind is offset, the bubbles affected by gravity will slowly float downward, so why do the bubbles blown out of the bubble machine rise first and then fall.
Whether it is a soap bubble blown out of your mouth or a soap bubble blown out of a bubble machine, when it appears, it will be heated and expanded. The hot air in the mouth or the heat generated by the bubble machine fills these soap bubbles with heat. The soap bubble membrane isolates the heat from the external air, making its interior a relatively independent individual. The temperature inside the bubble is higher than that outside. In the process of heating up, the internal temperature of the soap bubble will slowly decrease with the passage of time, and the reduction of temperature will make its internal density close to the density of the external air. When the internal temperature is consistent with the external air temperature, the buoyancy of the bubble will be less than its own weight. At this time, the soap bubble will slowly fall until it breaks on the ground and disappears.
Chemicals absorbed through skin contact may endanger children's health, lead to chronic poisoning, affect the reproductive system and cancer risk. In order to keep the liquid in toys for a longer time, preservatives will be added. Many preservatives are considered to be sensitized. If added in excess, children's long-term exposure or intake is likely to cause potential harm to their health.
