Finally, the second in our series promising to spotlight small inventions that make a big impact. Because just as we discovered when we added memory foam to a bath mat, small changes can significantly change everyday routines. This time out we look at the Starbuck’s splash stick. It’s a simple stir stick with a plug on top that seals the hole in the sip lid so when you’re walking your coffee doesn’t splash out onto your hand. The invention of the stick was the result of “crowdsourcing,” which basically means turning to the public for your ideas. Starbuck’s developed the stick after thousands of consumers turned to MyStarbucks.com in search of a solution to the splashing. The splash stick launched in April, 2008 to a fanfare of press, and while many complained that its one more piece of plastic destined for the landfill, the little stirrer stirred up mostly positive press for the chain. Today, the splash stick has become a part of many a commuter’s morning coffee routine.
