They built a better peanut butter jar!

Tired of wrestling around with a spoon and a butter knife to get those last bits of peanut butter or salsa out of the jar? This company has invented a clever jar that screws up from the bottom so that none of the goodness is left behind. It's still just a demo product, but I really hope it becomes a reality!
