This awesome, I mean disgusting, Petri plate is covered in microbes collected inside a Dyson hand dryer. The photo is grossing out plenty of folks on Facebook, but it doesn't mean that hand dryers should be #outlawed.

Dear Lifehacker, My bathroom at home currently has one of those heat-lamp and light fixtures with an inbuilt vent. The light in the center has died! How do I go about changing this? Where do I buy a new lightbulb that will fit in that? I am completely new to it and have zero experience changing lightbulbs.

If you have a porcelain bathtub or sink, you know how dingy they can get over time. You can keep them looking their best with a simple mixture of baking soda and ammonia.

The best ways to de-stink your stuff might not be easily available when discretion is the order of the day. If you don't want to leave a bathroom stinking, redditor RatherTall has a quick-fix concoction that he says masks the odours well when you're at someone else's place.

Cleaning up after a shave is a right pain in the bum. No matter how rigorously I rinse and wipe, there are always a few stray hairs that escape my notice (invariably to the vast annoyance of my wife).

A man in the US has attempted to "fizz the grime away" by taking a dip in over 300 cans of Pepsi. For reasons that deeply disturb me, I felt compelled to work out how much this carbonated bath would actually cost -- possibly so I can replicate it for a future Lifehacker article.

Humans are generally considered to be the most intelligent species on Earth. And yet, we choose to store our toothbrushes in the same room we shower and defecate in. What's that all about eh?

Most luxury body scrubs are simply salt or sugar blended with moisturizers. Why spend big bucks on something with such a simple recipe? Culinary blog TheKitchn took the principle ingredients from several DIY body scrub recipes floating around and put them to the test. They tried various mixtures of olive and essential oil blended with brown sugar, granulated sugar, and sea salt. Their findings? We preferred the granulated sugar mixture. It felt like smooth sand and provided good exfoliation without being too harsh. The brown sugar was clumpy and brown (lemony yellow seemed more aesthetically pleasing). The salt was too abrasive for our skin, although it would be great for calloused heels.
