Ghosts

Ghosts came to be in a strange but simple way deep in the tinfoil tunnels while experimenting on a new juice solution; our friendly mad scientist had been working for days and was in the middle of transferring the solution from the element to the boxing table when the whole batch slipped and spilled everywhere!! Gases glowing and weird smells started to take over the lab the smell was strong and glow was bright, but the strangest of all was the gas seemed as if it had taken on a life of its own! What is this new creature from the depths and is it something the mad scientist can make sense of?
