But for every brilliant life hack, there are surely plenty of duds out there that simply don't do the trick.
Fortunately for us, Mental Floss' John Green has taken it upon himself to test (and debunk) some popular life hacks -- so we don't have to.
Back in October, Green tested out several life hacks that he'd found on the Internet and this week, he's taking on 30 more.
In the clip above, watch as Green tries to turn a bathrobe into a Snuggie, to open a jar with a tennis ball and to make his own paint with stuff from the kitchen cabinet.
What works and what doesn't? Watch the video to find out.
