'Yes...' Nothing. Forrest preferred not to ccomplete his sentence, because he hadn't really seen any house elf magic. He smiled somewhat insecurely at the professor instead, and took down some notes as people mentioned spells. He kept his notebook on his lap, of course, so his writing was shaky and he couldn't keep up with everyone. He stopped writing completely in the end, because it was pointless. He could probably get a book or something from the library about cleaning after class.

Leaning forward as long as he dared to until he touched the table, he watched intently the professor's entire show, and he was left open-mouthed sliiiightly to see the table all clean and shining. Looking around though, he saw that no one looked that surprised, so he lowered his head and leaned back. He drew his wand from his bag and tried to remember Eliza's instructions.

'Try to imagine it clean...'

"Scourgify!"

Nothing happened like before.

Taking a deep breath, he pointed his wand from a different angle as if that would change the outcome.

"Scourgify!"

...some part of it was gone? Maybe? No? He was pretty sure there had been some dirt over there... he sighed, slapping his forehead as he shook his head to himself. Who was he kidding? He failed in the spell again. One last time, and he was done trying.

"SCOURGIFY!" he shouted, not caring whether he disturbed other people. The outcome? Success. "HA!" He kept beaming and looked around to maybe find someone to congratulate him, but no one was paying any heed to his success. His beam froze on his face. That was a little disheartening. Oh well.

Moving on.

Taking a deep breath, now that he was expert on scourgify, he drew a laaaaarge S as he said "Poliotus!" While it didn't shine like professor's, it looked better. Maybe it was the Sun's angle, maybe it was really the spell, maybe his eyes played games. Whatever the reason, it looked brighter to him and elicited another beam from the little boy, though he contained his voice level this time.

"Poliotus!" he exclaimed again as his wand drew an S, and got the full effect he wanted. His grin got wider, and he leaned back comfortably watching other people to see how they performed magic.
