The Stanley Tumbler Hack To Keep Venti Starbucks Drink Cold All Day
To keep your venti Starbucks drink cold all day, just pop the lid off a 40-ounce Stanley tumbler and slide your plastic cup inside. The cup fits flush with the rim of the tumbler.
This will leave just the Starbucks cup lid exposed for sipping. Thanks to this, your hands won't get cold, and your drink won't get warm.
Keep in mind that this hack only works with Starbucks' venti iced beverage cups and Stanley's 40-ounce Quencher tumbler. Other cups won’t fit well together.
