A vacuum is certainly in the top 10, however, one should never underestimate the thermos. If you put hot things in they stay hot. If you put cold things in they stay cold. Well how does it know?

Ah yes hayleighscomet, but after a while it won't be cold anymore and won't be hot anymore. While a vacuum cleaner will only collect more and more dust while it sits in the corner untouched.
