狂丸研究所，每天涨点新知识

最近天气实在是热得要命，出门在外空调太大拿不动，风扇小巧但要占另一只手，走在外头又变成了一种酷刑。

但最近，狂丸在网上看到有人用手机喇叭成功吹灭了一根蜡烛，非常神奇。

这要是真的，以后夏天出门可就太方便了，一边玩手机一边吹风，舒服。

经过一番搜索，原来，能让手机吹灭蜡烛的是一款叫做Blower（吹风机）的app，图标就是一个风扇和蜡烛，一看就是老blower了。

打开之后能看到界面非常的简单：像模像样的仪表盘搭配写着on/off的开关。

只要点击它，下面的轮盘就会开始加速旋转，发出临场感十足的嗡嗡声。

蜡烛也很配合，应声而熄。

如果搭配上另一个手机……这孩子，或许能拿来变魔术？.gif

除了吹蜡烛，这东西还可以当成一个迷你型号的、专门吹落叶的机器来用。

桌上的橡皮屑再也不会乱跑，都吹成堆儿一起清理掉。

反向改装一下，手机很可能就变成一个吸尘器了。

但众所周知，手机不是等等党梦里的那块原价显卡，一般里面是没有风扇的。

那这吹蜡烛的风，到底是从哪里来的呢？

还记得轮盘启动时手机发出的拟真嗡嗡声吗？我们都知道，声音由振动产生，但它本身是不能推动空气形成风的。

空气中的粒子只会像下图中显示的那样，在某个范围内波动，最终还会回到原本的位置。

这款app便是通过控制手机驱动扬声器，从而带动扬声器处的空气波动，从小孔附近一进一出形成力扑灭蜡烛。

app启动时将扬声器靠近火苗，就可以清楚地看到部分火焰呈现一个被吸入的趋势。

但虽然吸入和吐出时空气的量是相同的，可蜡烛并不会在空气被吸入时被吸力熄灭，因为空气被吸入时是来自吸取源的各个方向，大家没有心往一处想，拧成一股绳，没啥力度。

所以只有被喷出时比较集中，这才能保证蜡烛被熄灭。

视频中的老哥还用吸尘器和棉球做了个实验来验证这一点：棉球放在进风处纹丝不动。

而在出风口处，一下子就被吹跑了。

自此，既然掌握了声音才是这个app的神奇之处，那么如果找对相应震动频率的声音，其实不用这个app也能达到吹灭蜡烛的效果。

同样应用声音方面原理的还有那个号称手机进水神器的软件Sonic Ⓥ。

打开之后是这个样子的，只要按一下中间那个水滴按钮，调大音量，就能排出部分水分。

调到某些频率时，手指贴近扬声器真的能感觉到有气流吹拂。

确实有网友反应好用，把濒临溺死的手机抢救了回来。

不过，要是当场开不开机，还是拿去手机店修吧……

同理，那些号称有着给手机「物理清灰」能力的app和视频，其实都是用不同频率的声音带动空气来达到所谓的清灰目的。

至于清理能力是否真的有效，那就说不好了。

目前，那款叫做Blower的app在苹果商店售价12块人民币，感兴趣的朋友可以买来试试，不过要是吹蜡烛的话，我干嘛不用嘴呢？

郗委壮13351767691 ______ 方法很多,大致有隔绝氧气,风吹灭,让蜡烛烧完后自然灭,温度很低达不到着火点而灭......

丰仁鲁1386用嘴吹灭蜡烛是那种灭火方法 -
郗委壮13351767691 ______ 降低温度,吹出去的气流带走大量的热量,使得起火点的温度下降,从而使得火熄灭.所以如果我们是慢慢的哈气,蜡烛是不会灭的,尽管哈出去的气也含了二氧化碳.吹得越快,带走热量就越快,火越容易灭.

丰仁鲁1386供佛的灯还没有燃尽的话怎么熄灭它 -
郗委壮13351767691 ______ 用手指捻熄灭,注意不要用口去吹. 据寺院的法师讲,口气不洁,为恭敬故,用手捻熄.也有人讲,口气中含有众生,为免伤害众生故不能口吹.
