火烧屁股
嗯，不是火烧赤壁。原视频的标题是College Fart Experiment（学院放屁实验）。我起这个题目是有原因的：
屁,99%是由氮,氧,氢,甲烷和二氧化碳组成,另外1%中含有具有臭味的硫化氢.氢,甲烷,硫化氢都是易燃气体,根据摄入食物和每人身体的差异,屁的成 分组成比例会发生变化,当可燃气体的组成达到一定比例时一般会发生爆炸,而不是燃烧,因为燃烧需要可燃气体有较高的浓度.
所以咱们看到的不是真的，所以从视频本身来看，火烧屁股是贴切的，不信您看吧。

I like nonsense, it wakes up the wisdom cells. Fiction is a necessary ingredient in living, it’s a procedure of looking at freshness with the aid the bad ruin of a telescope. Which is what I do, and that enables you to laugh at life’s realities.

To be a noble lenient being is to procure a amiable of openness to the far-out, an skill to trust uncertain things beyond your own restrain, that can govern you to be shattered in uncommonly outermost circumstances pro which you were not to blame. That says something remarkably impressive about the prerequisite of the ethical compulsion: that it is based on a corporation in the up in the air and on a willingness to be exposed; it’s based on being more like a spy than like a treasure, something somewhat tenuous, but whose mere item attractiveness is inseparable from that fragility.

Celebrate the official ball not to mention
MBT Fanaka GTX
the confusion caused, and Green’s butter hand hilarious, even more English fans and cursing, while the same hand can be more than Green
MBT Ema sandals
butter one. Until after the second round group stage, the players seem to adjust to this ball, the score began to play big games changed the group stage goals in the first round of poor efficiency.
The most gimmick scene is associated with the
MBT Chapa GTX
ball, one crossing the line nearly 1 meter been blown out of the goal, led the 1966 Anglo-German fans for the review of old debts, but also led to the door, another wave of big wire technology discussion.
