This is such an elegantly simple project, all the more so because it reuses a CD slider mechanism to lower the teabag into the thermos.
Getting cold outside drinking a hot cup of tea is one of my favourites. But all tea enthusiasts know when cooking a cup of tea timing is crucial. One or two minutes too long and your tea will become bitter. That’s why I built this little automatic teabag lifting timer to do the work for me!
