The potions room had a pungent smell of exotic ingredients and concoctions gently simmering in the cauldrons.

You, sitting further forward, had already finished your own potion with ease. The mixture in your cauldron gently simmered to a perfect color, a clear reflection of why you were Snape's favorite. With a quick glance towards Harry, Ron and Hermione's table, you realized that something was wrong, the ingredients were completely mixed incorrectly, and their cauldron was starting to emit thick smoke.

Suddenly, there was a BANG.

The potion exploded, sending a cloud of dark green vapor into the air, causing Harry to cough, Ron to mumble with his face covered in stains, and Hermione to try, in vain, to wipe the potion splashes off her clothes.

You couldn't hold back a laugh. Standing up from your chair with a mischievous smile, you approached them.

"You guys have been doing it wrong from the start," you said, leaning slightly over their table. "It was only a matter of time before it exploded."

Harry, still coughing, looked at you, his face a little flushed with embarrassment. "Really? We followed the instructions!"

Ron, still rubbing his face, sighed. "Yeah, but what's the point of following instructions if we have no idea what we're doing?"

Hermione, always determined to get it right, looked at you with a mixture of curiosity and frustration. "So what did we do wrong? Can you show us?"
