Color Changing Christmas Lights Glass Cup with Bamboo Lid and Straw

A clear, can-shaped glass printed with a string of Christmas lights that sit pale and white while the glass stands empty, then fill in with red, yellow, green, blue and purple the moment something ice cold goes in. It comes with a bamboo lid, a clear straw and a slim cleaning brush, so an iced coffee on an ordinary afternoon gets the same small show as the drinks on Christmas morning.

No batteries. No switch. No strand of lights to untangle. Pour something cold and watch the bulbs come on.

The colors only come out for a cold drink

The bulbs are printed in an ink that reacts to temperature. At room temperature they read as soft white shapes on clear glass, with a dark wire looping between them and small white snowflakes and stars scattered around the outside. Fill the glass with iced water, cold brew or a soda straight from the fridge, and the bulbs turn red, yellow, green, blue and purple, like a strand of old-fashioned tree lights being plugged in.

Empty it and let it warm back up, and the white returns, ready for the next cold drink. The wire, the snowflakes and the stars stay the same the whole time, so the glass always looks finished. The change needs cold, which makes this a glass for iced drinks.

A lid and a straw for the drink you carry around

The bamboo lid sits on the rim and the straw goes through the hole in its middle, so an iced latte can stay on the desk or travel from the kitchen to the sofa without the top open to the room. The straw is clear and about 8.5 inches long, and the brush pushes straight through it after a milky drink, so nothing is left inside to go sour.

The glass is the familiar soda-can shape, tall and straight, with a gently rounded base and a slightly narrower lip that is comfortable to drink from without the straw. Choose from three sizes, from a small glass for juice to a large one that holds a full iced coffee with room for the ice.

Part of the decorations, even between drinks

On the breakfast table it turns a glass of cold juice into something that belongs with the tree and the stockings. At a party it gives every cold drink on the counter a little color, and nobody needs to be told what makes it happen, because they see it the moment the ice goes in.

Washed and dry on an open shelf, the white bulbs, the dark wire and the snowflakes still read as Christmas, so the glass earns its place on display until the next cold drink brings the colors back.
