Wand Weighing ceremony
From Harry Potter Wiki
The Wand Weighing ceremony was a traditional part of the Triwizard Tournament to ensure that all Champion's wands were in perfect functioning condition for the 3 Tasks ahead. During the 1994 tournament staged at Hogwarts School of Witchcraft and Wizardry, the Wand Weighing was performed by British wandmaker, Mr. Ollivander.
