Joy Dolo:我认为龙是神话中最酷的生物,因为它们有魔法,会飞,还会喷火。这引发了我对龙如何做到这些的思考,并希望能够在安全距离内观察到喷火的龙。 Sophia:我也很好奇如果龙真的存在,它们是如何飞行和喷火的。 Professor Mark Lorch:关于龙如何飞行和喷火,这是一个很棒的问题。我会尝试从生物学角度,而不是魔法角度来解释。我会参考其他动物的特性,看看是否能将这些特性应用到龙身上。首先是飞行,我认为最接近龙的动物是翼龙,它们在恐龙时代就已经存在,体型巨大,翼展很宽。虽然它们不像龙那样粗壮,但它们巨大的翼展足以让它们飞行。 至于喷火,我们需要考虑火的三个要素:燃料、气体和点火源。燃料可能是油脂,因为龙会吃很多动物,动物体内含有脂肪和油脂。龙可能储存这些脂肪和油脂,并像某些鸟类一样吐出油性物质。如果我们在这个混合物中加入额外的氧气,燃烧会更剧烈。点火源可能是龙吃下会产生火花的石头,或者像电鳗一样产生火花来点燃油脂。所以,龙喷火的方式可能是吐出燃烧的油脂。

Dragons are fantastical fairytale creatures that fly and breathe fire. They aren’t real, but there are animals that can do the things dragons do! So … if dragons *did *exist, how would they fly and breathe fire?  We asked science professor Dr. Mark Lorch to help us find the answer.
