You can also do the spells alternately, if you wish."
When professor Magnus finished speaking, Helena looked at her broken watch and the fancy looking quill. She wanted to keep the quill, so she'll practice the reversion spell on the watch. It was a good thing that the wand movement was simple. She tapped it twice, gently, then said "
Balterius." Welcome back, plastic bottle.
She scanned the bottle for a moment, then decided to turn it into something else.
Swish-to-the-left-and-gentle-tap, "
Covadium." Hello, brand new
green scarf! "
Pretty," Helena whispered, examining it.
