Here’s a kitchen gadget with a rather clever party trick: it can make a large round ice sphere and then transform into the cup you use to drink from.
The collapsible silicone cup is designed to be folded down for ice-making. Once the ice sphere is formed, pull the cup back open and use it as a reusable tumbler for cocktails, soda, iced coffee, tea, juice, or other drinks.

Why it caught our attention
The fun part is that you don’t need a separate ice mold taking up space in the freezer and a separate travel cup for the drink. One object handles both jobs.
The large round ice sphere is also considerably more interesting than ordinary ice cubes, particularly in a glass of something cold where you can actually see it.
When you’re finished, the cup collapses down to about 3.2 inches for storage, making it small enough to toss into a bag, car cup holder, or locker.
Good to know
The cup is made from BPA-free food-grade silicone and comes with a lid and reusable straw. The listing says the silicone is dishwasher-safe and that the ice sphere can be released by pulling the cup downward rather than handling the ice directly.
The lid is designed to provide a leak-resistant seal, although it should still be treated as a portable cup rather than something to throw upside down into a bag.
