But can you imagine wearing the same pair, five days a week, for three months without washing them?

Apparently, it’s okay. And if you already do, then you’re not alone. Researchers in Australia had 30 willing volunteers wear a pair of denims for the time indicated above without allowing them to wash it or have it washed during that time period. They were then conducted to a smell test, and surprisingly, they didn’t really smell that bad.

Melbourne University student Tullia Jack, who was behind the whole experiment, said: “You really don’t need to wash clothes as often as you think. Stains come and go, they just wear off.” And although some of the jeans had stains (motor oil, tuna, among others), they didn’t present smells that were “socially challenging.”

Jack believes her study, done for her Masters thesis, could have a huge impact on the environment. Just think how many liters of water can be saved, if we all pitched in and just washed our jeans once every three months. (Although I think I probably wouldn’t be comfortable going past a whole month without washing them… But we’ll see!)

Designers Sang Min Yu and Wong Sang Lee know how you feel, which is why they came up with the SavePaste Toothpaste Tube to help you get all that toothpaste out, minus the trouble.

My mom, who’s ever the recycler, hates seeing toothpaste go to waste, so what she does is cut up the tube in half right down the middle to scrape out the remaining toothpaste. Unfortunately, sometimes she ends up cutting more than just the tube and she’s walked away with a couple of mean cuts.

SavePaste will probably put an end to all of that, I’m sure. But more than that, the materials it makes use of are similar to the one that houses ready-to-drink milk drinks, which is more environmental-friendly compared to the metal-foiled plastic tubes that are in use nowadays.

It’s still a concept design for now, but it’s a pretty unique one at that. It also sets out to solve a pretty common problem that I’m sure a lot of people all over the world encounter at least a few times in their life.

Who knows? Maybe we might be seeing our toothpaste in new packaging soon.

When my baby teeth began falling out, my mother scared me into thinking that it was because I hated brushing (which is, technically, true) and I freaked out with her exaggerated stories (I was going to be toothless by age 30, she said) so I got my act straight and became a religious brusher ever since.

However, for those people who have yet to learn their lesson, the Misoka toothbrush is here to save you and your mildewy teeth.

So what makes this plain-looking toothbrush so special? Well, its bristles are coated with a nanomineral that will not only remove all the gunk from your pearly whites (or uh, yellows) but also leave a hydrophilic coating on your teeth to prevent any detritus from sticking to your teeth.  In normal-people speak, hydrophilic means “water loving” (or in this case, saliva loving) and detritus refers to all those tiny particulates that give you cavities and sore teeth if you don’t keep them away (in short, teeth gunk.)

Imagine all the water and toothpaste you’ll be able to save by just having to brush just once a day! The thought of brushing with that (in)frequency doesn’t sound very appealing to the adult me, though. The Misoka toothbrushes go for $15 a pop from the Hiroshi Beverly Hills Salon.

The Zapi uses ultraviolet light to clean your toothbrush “in minutes”. Let’s hope that’s not more than 5 minutes. Since we can’t see the actual cleaning process, Zapi bobs enthusiastically as proof of the intense 99.9% cleaning action going on inside. It has a removable drip cup so you can easily clean it. So what cleans your teeth? Your toothbrush. What cleans your toothbrush? Zapi. Who cleans Zapi? You. Someone invent a Zapi Zanitizer.

The VioLight Zapi toothbrush sanitizer sells for $30 USD at Amazon. As you can see it comes in 4 colors, and includes a free matching toothbrush. It runs on three AAA batteries, not included.
