Things my cat puts in her water bowl. If

Here we go again. She must be so proud of herself 😂
Another hairband and the cross thing again.

Does anyone know why she keeps doing this?
Both cats still drink water from the bowl even with the things in it and it kan be all kind of stuff she drops in there.
So far I've found a USB stick, wristwatch, numerous hairbands, small candle lights and I don't remember what else. Something new almost every day.
