Non-cooks think it's silly to invest two hours' work in two minutes' enjoyment; but if cooking is evanescent*, so is the ballet. 
 Julia Child 

When we are short on the real ingredients, or are recovering from a sugar-laden holiday, play dough  substitutes fabulously for the sugar and butter and flour (we still use real sprinkles though).

The play dough versions provide a greater variety of treats that we haven't yet figured out how to make in real-life.   

* I had to look up evanescent.  It means:   vanishing; fading away; fleeting or tending to become imperceptible; scarcely perceptible.
