Meet the World's Smallest Fruit

It's easy to be impressed by big things. The blue whale, the African elephant, and the giant sequoia are all easy to spot, if you ever get lucky enough to see them in person. But sometimes the smaller things—particularly the things that you can barely see with the naked eye—get overlooked.

Even so, there can be no doubt that the Wolffia globosa is an impressive plant, even if it would look like a tiny speck in the palm of your hand. Better known as Asian watermeal, it's the world's smallest flowering plant, less than one-third of an inch wide at its largest.

A kind of duckweed, Asian watermeal grows quickly, spreading across the surfaces of bodies of water at an incredible rate, floating without needing roots, stems, or leaves to survive. Mainly it reproduces asexually, but very occasionally it flowers, and from the flowers comes the smallest fruit in the world, known as an utricle [PDF].

You'd be hard pressed to feel full on a meal of utricles, given how tiny they are, but they are edible, as is the whole plant (although separating the fruit from the plant might be a bit of a challenge). In fact, duckweeds are already cultivated in Southeast Asia for food and are high in protein; duckweed has been vaunted as a new and plentiful food source for us all, given how quickly it multiplies. Apparently, it tastes a little like watercress.

This mighty microplant is also being investigated as a possible energy source. As a biofuel, it would be carbon neutral, as it removes carbon dioxide from the atmosphere. Additionally, it could be used to purify water, balancing levels of phosphorus and nitrogen; it can also pull both arsenic and cadmium from the environment.

To cap it all, Wolffia has been investigated as a possible food source for long-term space travel. For a speck of a plant that's easy to miss, it has some big potential.

If you'd like to give it a taste, here's a recipe from Recipes Thai Food for a watermeal omelette.

Swear Off Toilet Paper With This Bidet Toilet Seat That's Easy to Install and Costs Less Than $100

The recent coronavirus-related toilet paper shortage has put the spotlight on the TP-less alternative that Americans have yet to truly embrace: the bidet.

It's not exactly a secret that toilet paper is wasteful—it's estimated to cost 437 billion gallons of water and 15 million trees to produce our yearly supply of the stuff. But while the numbers are plain to see, bidets still aren't common in the United States.

Well, if price was ever the biggest barrier standing in the way of swearing off toilet paper for good, there's now a cost-effective way to make the switch. Right now, you can get the space-saving Tushy bidet for less than $100. And you'll be able to install it yourself in just 10 minutes.

What is a Bidet?

Before we go any further, let’s just go ahead and get the awkward technical details out of the way. Instead of using toilet paper after going to the bathroom, bidets get you clean by using a stream of concentrated water that comes out of a faucet or nozzle. Traditional bidets look like weird toilets without tanks or lids, and while they’re pretty uncommon in the United States, you’ve definitely seen one if you’ve ever been to Europe or Asia.

That said, bidets aren’t just good for your butt. When you reduce toilet paper usage, you also reduce the amount of chemicals and emissions required to produce it, which is good for the environment. At the same time, you’re also saving money. So this is a huge win-win.

Unfortunately, traditional bidets are not an option for most Americans because they take up a lot of bathroom space and require extra plumbing. That’s where Tushy comes in.

The Tushy Classic Bidet Toilet Seat.

Unlike traditional bidets, the Tushy bidet doesn’t take up any extra space in your bathroom. It’s an attachment for your existing toilet that places an adjustable self-cleaning nozzle at the back of the bowl, just underneath the seat. But it doesn’t require any additional plumbing or electricity. All you have to do is remove the seat from your toilet, connect the Tushy to the clean water supply behind the toilet, and replace the seat on top of the Tushy attachment.

The Tushy has a control panel that lets you adjust the angle and pressure of the water stream for a perfect custom clean. The nozzle lowers when the Tushy is activated and retracts into its housing when not in use, keeping it clean and sanitary.

Like all bidets, the Tushy system takes a little getting used to. But once you get the hang of it, you’ll never want to use toilet paper again. In fact, Tushy is so sure you’ll love their product, they offer customers a 60-day risk-free guarantee. If you don’t love your Tushy, you can send it back for a full refund, minus shipping and handling.

Normally, the Tushy Classic retails for $109, but right now you can get the Tushy Classic for just $89. So if you’ve been thinking about going TP-free, now is definitely the time to do it.

The Clever Reason Oranges Are Sold in Red Mesh Bags

If a detail in a food's packaging doesn't seem to serve a practical purpose, it's likely a marketing tactic. One example is the classic mesh bag of oranges seen in supermarket produce sections. When oranges aren't sold loose on the shelf, they almost always come in these red, mesh bags. The packaging may seem plain, but according to Reader's Digest, it's specially designed to make shoppers want to buy the product.

The color orange "pops" when paired with the color red more so than it does with yellow, green, or blue. That means when you see a bunch of oranges behind a red net pattern, your brain assumes they're more "orange" (and therefore fresher and higher quality) than it would if you saw them on their own. That's the same reason red is chosen when making bags for fruits like grapefruits or tangerines, which are also orange in color.

For lemon packaging, green is more commonly chosen to make the yellow rind stand out. If lemons were sold in the same red bags as other citrus, the red and yellow hues together would actually make the fruits appear orange. Lemons can also come in yellow mesh bags, and the bags for limes are usually green to match their color.

Next time you visit the supermarket, see if you can spot the many ways the store is set up to influence your buying decisions. The items at eye-level will likely be more expensive than those on the shelves above and below them, and the products near the register will likely be cheaper and more appealing as impulse buys.
