"An Insulating Charm. Wish I had thought of that!" Sam scolded herself internally.
She listened attentively to Professor Fuller as he discussed the incantation and the precise wand movement. She took out her quill and a piece of parchment and wrote down a couple of notes.
Sam placed her quill on her desk and began to mutter the incantation.
"CAY-lum - SAY-pee-oh" she said over and over again, making sure that she was pronouncing the incantation correctly. Sam continued for another two minutes until, finally...
"Caelum Saepio"
Sam felt satisfied but she hoped that she had done things correctly.
