The tank was a sound and light insulated capsule about the size of a compact car—it contained body temperature water, saturated with Epsom Salt, about a foot and a half deep.

这个舱是个隔音隔光的胶囊，大约相当于辆紧凑型汽车——里面装有温温度的水，水中饱和溶解了硫酸镁，水深大约英尺半。

To do that, you just stick a few seed crystals into water saturated with dissolved sugar.

要实现这，只需将几颗种子晶放入已溶解了糖的饱和水中即可。
