As we all know, bubbles can not only play play, but also ... | Play seriously

Everyone has played with bubbles
But the bubbles are very fragile in the impression of the editor
Break down when you touch it lightly
However, today we are going to play the bubble as a ball
Don't come to watch yet
experiment equipment
The marked cup, corn syrup, starch, bubble powder, dishwashing, cup, wire gloves, electronic scale
experiment procedure
First of all, we are ready for the following dosage raw materials
Then, mix these raw materials and mix well
Get such a cup of strong bubble water
Unlike ordinary bubble water
Bubble made with strong bubble water
Not only can it be kept on the gloves for a longer time
You can also use your hands to "Ball the ball"
Call your friends to play together
The most time than whom the ball is
Original understanding
Washing essence is a kind of surfactant. It is hydrophilic at one end and water sparse. When a bubble is formed, the hydrophilic group of the surfactant facing the solution, and the hydrophobic end faces the air. Due to the effect of gravity, the water on the top layer will always flow down, which leads to the thinner and thinner film of the top layer. The motion of the external motion of the outside world will cause the membrane to wrinkle, which will rupture.
Corn syrup can absorb water molecules from the air, reduce the evaporation of water molecules in the bubble, and at the same time, starch particles covered outside can inhibit drainage caused by gravity. Under the common effect of the two, the life of bubbles increases.
Human skin will secrete some oils, and these fats will destroy the balance of the surface tension of the bubble and break it. The use of cleanline gloves not only avoids the effect of oil, but also because the surface structure of the fiber fabric has more gaps, more hydrophobic, and small contact area with bubbles. Therefore, when the bubbles are pushed with gloves, the bubbles are not easy to break, and it is not easy to attach to the fabric, which can bounce again.
