You know that moment when there is just enough ketchup left in the bottle for your fries but no matter how much you jiggle it, pound it, dig your knife in it, you just can't seem to get it out? Well, fret no more. Thanks to MIT PhD candidate Dave Smith and a team of researchers at Varanasi Research Group, there will be no ketchup left behind.

MIT didn't determine the secret angle for optimum results or the correct velocity of smacking. Instead, they developed a slippery non-toxic coating that helps speed up the process. The answer to all ketchup frustrations: LiquiGlide. 

 

LiquiGlide is made from FDA-approved materials and can be used to coat the inside of a variety of surfaces, glass or plastic. It took two months at the MIT lab to solve this ketchup conundrum and its sweet victory was worth it. LiquiGlide came in second place in MIT's $100K Entrepreneurship Competition and Smith's team took home the audience-choice award. 

The next challenge for the team: to sell the invention to companies that make sauces. 

Watch it in action, here.
