You know, when you say 'it's raining, stay inside' most people listen. They know the rain is bad for them. Some on the other hand are
stupid. Some aren't quite that stupid, but are still pretty brainless, barreling out the rooftop doorway with an alchemically created metal shield against the rain. There's hurried clap-flashing and the soil samples in the glass jars Ed has been laboring over are moved to his waiting arms and hurriedly transported into the building, just in case... but all the plastics (they'll have to be reinforced, shod in steel next time) and other goods are... pretty much shot.
A little worse for wear now, there is a very frustrated but still quite dry alchemist sitting at the stairs to the roof. Emo doesn't quite cover it; his head in his hands, his hair fallen down to hide his face, Ed is so very frustrated he could almost cry. They had worked so hard and so long... Just when they were about ready to get it running...
Life, well, life's what happens when you're making plans, isn't it? Ed should know that well enough. Doesn't make this setback any easier to swallow.
