一说起“法老之蛇”,你一定会毛骨悚然,后脊发凉,然后问我为什么会做这么可怕的实验,确实“法老之蛇”实验是一个经典的膨化实验,名字的来源于它让人不寒而栗的外形,像极了一条黑乎乎的蟒蛇。

一天,我闲来无事,不停地在房间里溜达,不经意间我看见了书架低端布满灰尘的实验书。我拂掉灰尘,打开书,在微微泛黄的目录上寻找,我的目光在上面跳跃,最后在一个名叫“法老之蛇”的实验上停住了,我的脑海里一下就蹦出了许多问号,为什么叫“法老之蛇”?它有什么秘密吗?这便让我来了兴趣。在好奇心的驱使下,我翻到了对应的页数,这个实验只需要白砂糖、苏打粉、医用酒精、沙子和盘子。我从厨房拿出了白砂糖、苏打粉和一个铁盘子,又从医药箱里拿出了医用酒精,最后去阳台上把妈妈的肉肉花盆里的细沙倒进盘子里。这些材料十分常见,让我觉得它们根本做不成“法老之蛇”。我按书上的步骤一步步做着,先把白砂糖捣得更细更碎,然后倒入苏打粉和细小的白糖末拌均匀,接着将酒精倒入沙子,不一会儿酒精便被沙子吸收了,消失得无影无踪,就如同向几百摄氏度的石头上浇凉水,最后将满分/它们混合,让我爸爸点上火,大功告成!

摇曳的火舌吐着橙红色的火星,火中隐约看见一根黑色的小棍,十几秒后它已经有我手指粗细了,但它还在“生长”,越来越粗,越来越长。一旁还有许多黑乎乎的小棍,似乎簇拥着它,而它傲视群雄,表示对它们的不屑。几分钟后火熄灭了,盘子里就像一片“黑石林”,里面尽是形态各异的“怪石”:有的“长”得笔直,似乎想把天捅出一个窟窿;有的“长”出盘外,如同一只黑色的巨蟒缠在透明的枝丫上吐着芯子向下张望;有的刚“长”出来,有很多小裂纹,和我妈妈那株刚破土而出的生石花有几分相似。

我想为什么它是黑色的?它是怎么形成的?我的好奇心又在作祟,我拿出书本寻求答案。翻开书,我恍然大悟,原来因为苏打粉遇火会产生二氧化碳,而它能让糖燃烧生成的碳固化成多孔蓬松的碳柱。在这个实验中酒精是用来助燃的,糖和苏打粉是产生碳柱的原料,沙子则是用来隔热的。
