I wasn't a murderer but I accidentally murdered someone with a blunt knife, which magically turned sharp in his belly. The entire story of the murder died along with the person.
Now the biggest problem was that I didn't want to go to prison. My mind was dumb, I couldn't find a perfect place to get rid of the corpse with proper disposal of any evidence against me. With no idea in my head, I decided to take the corpse to my apartment and thought to plan something when I would get home. I needed to escape anyhow.
Without anyone's notice, I successfully got in my apartment with the dead. Somedays passed and still I couldn't come up with any idea and even worse, the awful smell from the corpse was bothering my nostrils all the way.
After continuous scratching of dumb head, my cerebrum hit the idea of preparing formalin. God knew why I had this useless idea which had nothing to do with my escape. Might be my dumb mind went to a different paradise of preserving the deads.
Fortunately I had some tomatoes in my refrigerator which I had collected in open singing event. Actually, the audience liked my singing so much that they threw some tomatoes in appreciation. Very carefully, I extracted the oxalic acid from those tomatoes. Alas! I wasn't having another ingredient, the glycerol. My dumb mind (or evil or cunning you say) snored and very cleverly I stole glycerol from the chem girl next door.
All the ingredients were on the desk. With a dumb grin on my face, I started the preparing formalin with my gloved hands. Oxalic acid and glycerol were mixed and boiled at 100°C. After few minutes of heating, I felt little oddness in the air. It wasn't normal. I detected that carbon dioxide was born and it got escaped in the air.
But my dumb mind didn't care to wear any mask at that time and happily took out the product "Formic Acid". I tried to treat the dead body with it but to my heavy astonishment, it didn't work as expected. I was devasted.
Again of continuous scratching of my head, my dumb mind finally realised that formalin meant "formal dehyde" and I had prepared formic acid. I had no choice left other than beating my forehead and cursing my dumb mind.
In the midst of cursing my dumb mind, I saw a peculiar shadow lurking behind the curtains. It was whispering "Learn the organic reactions properly."
