Helga sat down next to her and opened her books.
"Okay class, today we'll be making clear glass red. It won't be difficult, it will be a small piece. If you all have studied, I'm sure you can complete this task." She said and waved her wand. Multiple small crystal clear glass balls appeared on each table in a neat pile.
Chloe looked worried. She hadn't studied. She took her wand out, muttered the spell, and tapped the glass. Nothing happened.
