Diet fads come and go, but most have at least one element in common: the requirement that individuals be deliberate about what they eat (rather than ravenously consuming everything like a starved beast).
Unfortunately, it’s difficult to have self-control when food is delicious and plentiful.
Thus, most people eat larger portions of food than they really would if they ate a bit slower (as has been discussed previously).
To encourage people to stop eating before they are absolutely 100% full, the following technical solution is devised: “clockwork utensils” that change shape over time (thanks to a spring inside).
This spring must be wound up before use: then, over the course of a few minutes, it unwinds and turns the normal utensil into a bizarrely barely-useable piece of abstract art (see Figure 1 and Figure 2).
Instead of buying a new set of silverware, you should put that money towards funding a manufacturing project to create the utensils describe above!
PROS: Could reduce over-eating!
CONS: May promote binge eating. It may also be difficult to wash the tiny mechanical parts of such a utensil.
