From Lifehacker:

There
s a big trend right now in kitchen gadgets to make things out of silicone. It
s a versatile, flexible material and some designers have figured out you can also produce collapsible items with it.

From Coolhunting:

Set of four measuring cups, $19.95 from Solutions. Funnel and colander, designed by Boje Estermann and inhouse designers at Normann Copenhagen.

May we also suggest collapsible wok, table, and coffin? All, if pocket-sized, great for hiking.
