If you’ve ever enjoyed a hot cup of coffee or cocoa poured from a thermos hours after it was made, you might owe William Stanley Jr. a thank you. He invented the vacuum bottle back in 1913, and his products have become iconic in the decades since. One of them, the 1.5-quart insulated thermos, is on sale as a Prime Day Lightning Deal for 51 percent off. It’s made of 18/8 stainless steel and will keep liquids hot or cold for more than a day. Grab one for $19 before the day is over.
