Here's a funky one; Penguin tea bag timer / dipper from Küchenprofi. The function of it is simplicity itself; you hang the bag to the beak, set the time of how long you want the bag to remain in the water and pull the beak down. When the time runs out, the bag is lifted up.
As someone who, as I've told several times, has a habit of loosing sense of time when I start working on something, this is a tiny marvel. So many times I've 'over dipped' my tea because I got lost into TAGAP dev somewhere, but not any more. Huge thank you to the colleague who discovered this – it's proper taste-saver.
