You Know You Need One: A Lock for Your Nutella Jar

Most consumers believe that Nutella hazelnut-chocolate spread is sold in single-serving containers — as soon as they open the 35-ounce jar, they finish the whole thing. Thankfully most consumers can’t buy the 6-pound foodservice size. The gooey stuff is addictively tasty but it’s mostly sugar and palm oil, so it’s pretty unhealthy.

Help is on the way. Germany’s Daniel Schobloch has designed the Nutella Lock, an acrylic device that fits over the jar lid so it can only be opened with a key. He says it’s so your kids won’t eat all the Nutella, but we know better, don’t we?

Nearly 1000 of the gadgets have already been sold on German eBay at €9.99 ( $11) each. We expect to see a high-performance alloy version at Williams-Sonoma any day now.

A research team lead by Cornell University marketing professor Brian Wansink and his brother Craig Wansink, Professor of Religious Studies at Virginia Wesleyan College, analyzed 52 paintings of the Last Supper painted from 1000 AD to the 1700s. They found that the size of the meals and plates increased over time. Brian Wansink, author of  Mindless Eating, calls this “proportion distortion.”
