Having just discovered a pile of sugar at the bottom of my [bitter]
cup of cocoa, I propose a device which ensures that all the sugar/
coffee/salt/copper sulphate in a mixture has been dissolved. This
could be done in a number of different ways:
Number 1: The Indicator - this rod-shaped device
uses SONAR to
check whether all the solute has dissolved. Press the button on top
to
activate - if it beeps, you still have solid in there.
Number 2: The Attractor - this uses static electricity to attract the
solid towards it - you can then remove it from the solution to see
how much solute is still needing to dissolve.
Number 3: The Crusher - similar to a paintbrush, only the brush
itself
is rotating - simply press into the bottom of the container and stir.
Number 4: The Zapper - this simply sends a wave of heat through
the
bottom of the container, instantly dissolving any leftover solid.
Will It Dissolve?

Hmm. Only 4 of your proposed solutions (hah!) have
problems. |
|
| |
1) I'm not sure how effective this would be for small grains
sitting on a solid surface. Also, given the dimensions of
the cup, I wonder if echoes from the walls etc would be
so fast as to confuse it. |
|
| |
2) I don't think this will work under water |
|
| |
3) How does this achieve what your teaspoon failed
to achieve? |
|
| |
4) How? Also, assuming your cocoa started off at a fairly
high temperature, further heating is unlikely to "instantly"
dissolve residual solute. |
|
| |
Apart from that, they're all good. But why not simply feel
with the teaspoon whether there is undissolved sugar, and
then stir until it dissolves? |
|
| |
As crystallographers say, if you're not part of the solution
then you're part of the precipitate. |
|
| |
If only there were a device that could agitate the solution to encourage the dissolving process. |
|
| |
Perhaps if there was some sort of syrup.... |
|
| |
The other Indicator: A glass container to hold the drink. |
|
| |
The other Crusher: A spoon. |
|
| |
the other Zapper: A microwave. |
|
| |
Although I do see the beauty of your indicator and attractor. |
|
| |
Obviously the simplest solution is to use a cup or vessel in which the bottom is a transducer, emmitting an untrasonic (or perhaps E-M) signal at the right wavelength to disperse a sugar crystal. There must be a resonant frequency for sugar that would set up destructive resonance within the crystalline structure. |
|
| |
Learning to like things bitter at first may be simpler. |

Number 6: Ask a diabetic... (not sure but a clinistrip might work) |

What you need is mortar and pestle china. |

|
| |
That would be cheating. This is the Halfbakery, and the rules say you need a Rube Goldberg contraption for this kind of job. |
|
| |
Also, have you ever tried getting a spoon into the corner of a
mug? |

This is something that most people "do" rather than "try".
Basically, I'll try to explain. Your spoon (at it's business
end, the end you ought to have in the mug) has a sort of a
bowl shape. You need to hold the spoon so that the distal
end of it is in the corner of the mug, with the handle (the
holding-part) sloping inwards toward the centre of the mug
at an angle of about 30 degrees. |
|
| |
The important point, and perhaps where you've had
problems, is to have the conCAVE side of the bowl facing
outwards and upwards. |
|
| |
If you maintain the spoon in this orientation, but move it
as a whole as far outwards and downwards as it can go
without applying undue force, you will find that the tip of
the bowl comes to rest in the bottom corner of the mug. |
|
| |
You may find it easier to practice with an empty mug first,
before trying this "blind". |

Hahahahahahahahahaaaaa.... |

<wipes eyes> That is one of the funniest things I've read all
