It was a powder made in the laboratory. It was a powder to kill the aliens that had taken over years ago. It had a poisonous chemical in it that was burning hot. It could burn you so bad that the aliens would melt if they drank it. It looked just like a glass of water but it was way more dangerous. The professor took the glass of liquid out of the cooler fridge and walked out the door. Not many seconds later we heard the roars and cries of aliens. There was a few thumps on the door and then it opened. The professor was cut and bleeding but muttered slowly “we did it”.
