Brilliant! The office will look much more cheerful with those!

Your comment has, I hope, sent me on the right track.
I think back to those old Aussie movies of Old Aussies Boiling The Olde Aussie Billie and swinging the billy in grand circles (usually in a vertical plane) to settle the leaves, and thought, "What if I were to spin on my vertical axis at a high rotational rate, holding the mug at arm's length with the base farthest (US: furthest) away from me. Centrifugal Force (Rudi was on the right track!) should keep the mug full until I (gracefully) slow down my rotation as I reach the chair in which I am supposed to sit, in one fell swoop.
No wait! There's More!!
What if I mounted the bicycle wheel on a trolley platform and stepped onto the bike wheel; a motor starts it (with me) spinning (subroutine to Centrifugal Force above) and with my spare hand I push off from the kitchen and roll horizontally on the trolley while rotating at high speed on the bicycle wheel platform.
Before crashing into my chair.
OK. needs a bit more work ....

(1) My mugs are not cylindrical; they are tapered, narrowing towards the base and
(2) I'm not tipping the container at all (excepting see "chair" above), just trying to walk steadily holding the mug as close to vertical as I can.

Rudi, that's the last straw! Did you really have to post that picture?

Forget spinning wheels and half-naked straws, what you actually need is a gimbal.

Re: A physics problem
That's exactly what I was thinking for a non-spinning solution. A holder with dual axis: The cup (purple) is held by two metal rings (dark and light blue) rotatable around the two axes (red). When held by the handle (green) gravity will hold the cup upright due to the weight of the cup and tea.Leif wrote:Forget spinning wheels and half-naked straws, what you actually need is a gimbal.

Re: A physics problem
There are plenty of gimbal cup holders, but they're not for walking around - they are for use on a boat or perhaps a car, fixed to mast or dashboard.
This one is for holding in your hand, but it doesn't seem to work very well: Double Gimbal Drink Holder: NEVER spill your Root Beer!

Re: A physics problem
Not really. The cup is attached to the gimbal ring above the center of mass, but doesn't have to be attached at the lip.Leif wrote:Impossible to drink out of though - you'd need a straw...
Hans, those are cup holders. This is the cup itself for the "steady" challenged among us!

I just tried this.BobH wrote:Don't look at the cuppa. ...
Not watching the mug while you walk does not obviate the spillage; it merely means that you don’t see it spill which, providing it spills on an expensive Persian rug or similar pattern, means the spillage is undetected, leading one to the false conclusion that spillage did not occur!
