It's the most successful Kickstarter campaign ever. The Coolest Cooler (yes, a cooler) raised $13.3 million in its 52-day run. The previous record holder, the Pebble smartwatch raised $10.2 million in 2012. Why have more than 60,000 people contributed to a cooler campaign? Well, this cooler includes a blender, waterproof bluetooth speaker, USB charger, cutting board and bottle opener -- a "portable party," according to founder Ryan Grepper of Portland, Ore. And those who pledged enough ($165 or more) will save at least $130 on the cooler, which will retail for $299. Those who contributed less can still get in on a piece of Kickstarter history: A $25 contribution earned a Coolest-branded reusable party cup and a drink guide; for $55, backers receive the party cup plus a "Keep Calm and Blend On" tee.
