Show how much spell power the user have
A Magical Measurer is a device similar to the Muggle High Striker. The Magical Measurer is used to measure the power of a spell: if the device is struck with a spell of enough power, the puck will rise high enough to hit the bell. The Weasley family and Gambol and Japes Wizarding Joke Shop owned one each.
