A beautiful turquoise glow emitted from the ends of their wands and swirled around and through the bubbling potion. It lasted for a moment before the colour faded and the potion stilled, clear as crystal. Hermione looked up at Snape, who nodded and turned off the flame beneath the cauldron. They removed their wands from the brew, and Snape grabbed a silver spoon, scooping out the crystal liquid and using his hand to waft the scent to his nose. It had a very strong scent, similar to the Old Spice Hermione could remember her grandfather wearing from when she was a young girl.
