as the world of technology is growing, the people of britain are getting lasier so lazy in fact that gaget companies think it would be appropriate to take the long hard stirring process out of making tea.
I thought of a self-stirring mug, and found that you can get one; great stuff! I thought of it because then it's my own mug at work (not a shared one), and the teaspoons are sometimes not clean enough for me. If I bring a teaspoon, it's just going to get mixed up with the ones at work, this simply avoids that problem. So it's not about laziness...
Mine was actually metal. but called "self stirring mug" on the actual product. I checked and it seems like it shouldn't leak into the motor AS LONG as you only use it with a liquid in it. And rinse it out with clean water after and before each use to keep it running smoothly. The inside is plastic but the "metal looking outside" is actually metal.. Mine seems to have a sturdy handle.. but runs on triple A's instead of double A's.. and so I use NIMH rechargeables for more speed and power and make it last longer.
