Even as adults we still enjoy blowing bubbles, don’t we?
即使我们已经成年但却仍然喜欢吹泡泡,对吧?
If you’ve ever wondered why blowing on a thin film of soapy water creates bubbles, this is your lucky day.
如果你也曾好奇为何肥皂水薄膜能吹出泡泡,那么今天就来帮你解惑C;wu-QAs_c10|;Ya^&
All liquids have a property called surface tension. Take water, for example.
所有液体都有“表面张力”的特性,水也不例外#D[MLv&)hrIYI~yCZI;
Water molecules are strongly attracted to each other.
水分子会相互吸引Fp7X#ukA4jpZh!;d

Therefore the molecules on the surface of the water are not attracted towards the air, but rather towards the rest of the water.
因此,水表面的分子会被其余的水分子吸引,而不受空气分子吸引;N%-JX#80FbWg~
This attraction is what creates surface tension, forming a sort of skin on the water’s surface.
这种引力引发表面张力,继而在水面形成一层类似皮肤的薄膜!5*l2mZz0h31;yS
Surface tension is also what accounts for soap bubbles.
表面张力也是肥皂泡的成因_&JfB5&XfFI!zR3HJ
Dipping a wand into regular water won’t work because the water’s surface tension is so strong that the molecules would rather bunch together in a puddle than be stretched across the opening of the wand.
将“魔术棒”放入水中浸泡后无法吹出泡泡,这是由于水表面的张力太强,水分子会凝聚在一起,无法在“魔术棒”的开口处拉伸B(iP%3Nf|81_
