For a magical wand, a drumstick is unlikely to work. Magical wands are usually associated with specific materials and rituals in fictional worlds, and a drumstick wouldn't fit that.
For a prop wand, it might work, but it's not ideal. A drumstick is likely to be too thick and heavy to be comfortable to hold and maneuver like a traditional wand. The material might also be too rigid, making it difficult to perform certain wand movements.
However, if you're just looking for something to use in a playful or casual way, a drumstick could work. It's a fun and readily available object, and you could certainly use it to pretend to cast spells or perform magic tricks.
Ultimately, whether a drumstick works as a wand is a matter of personal preference and the specific purpose you have in mind.
