The kid could be a very curious one. He's the type who is always exploring and not afraid to try new things with the can. He might be constantly looking for new objects to test if the can can make them disappear.
It could be a high - tech can. Perhaps in this short story, the can is a device from the future or an advanced alien technology. The kid, being curious, figures out how to operate it and it emits a ray or energy field that causes things to disappear. The can might have some kind of interface or button that activates this disappearing function.
The kid might be using the can as a prop for a magic trick. Maybe the can has a false bottom or a hidden compartment where the objects are secretly stashed to make them 'disappear'.
Perhaps the can has a special mechanism. For instance, it could have a button that when pressed, creates a suction force and sucks in the small objects, making them disappear.
