If you've seen some of the tips and hacks we've posted and wondered if they actually work, check out this video from Mental Floss. John Green put 30 different life hacks to the test with some surprising results.
It might look like he's out to debunk every one he tries, but keep watching -- you'd be surprised how many of them actually pass (often with hilarious results). The ones that fail often fail because he's either not doing them correctly, not doing them very well, or just because they don't work in every situation (For example, folding a fitted sheet may fail in the video, but it's really not hard to do correctly).
Some of the others though, like chilling a beer by wrapping it in a towel and the right way to amplify your phone's speaker (hint, it's not by sliding it top-down into a toilet paper tube) are solid tips we've covered before, complete with the science behind how they work. Still, most of the hacks pass, and if you take the fails with a grain of salt (and look up how the trick is supposed to work), it's a great demonstration of the more popular life hacks out there.
