Fish can see 180 degrees on each side of their heads. The only blind spot is behind their tails. They can also see into the ultraviolet spectrum. And yes, your goldfish can see you quite well, even though it’s in water and you’re on the other side of the glass in air.

Rabbits have extremely strong hind limbs which allow them to leap great distances. How high they can jump is debated, but they can jump over 2 ft (0.6 m) high, and possibly up to 4 ft (1.2 m). Rabbits can leap up to 9 ft (2.7 m) horizontally.

An old way of tanning leather hides was to use the animal’s own brains as the agent. Actually I don’t really know what “tanning” means. Preserving and softening the hide, rather than letting it rot, or dry out and get stiff? In any event, the story is that, whatever the animal, the amount of brains matter is just enough to tan the hide. So the saying/joke is “Every animal has just enough brains to save its own skin.”

Airflow is important to a PC’s cooling system, and more airflow means cooler temperatures as proven in this video by “strapping” two singular horsepower fans to a computer. The positive up side compared to liquid cooling is that it cools every component in the system at once, rather than what the pump and pipes are connected to. The major downside is the power draw and, of course, the noise. Other extreme measures have proven to be just as beneficial if not more so, where a bigger heat sink (as shown in this video), was enough to allow a PC to run Crysis skybox for a few days without thermal throttling and having no fans.
Airflow solutions like these (and that custom “goo” that goes on the CPU in the heat sink’s case) have proven to be better than (or at least less damaging to the components) liquid cooling. Although better, hardly anyone wants a 90 DB or, I believe, a 100 LB PC.

Blood is repelled by magnets.
Well that’s half a truth… water is repelled by magnets and since there’s a lot of water in human body, we can claim that people are repelled by magnets…
…but the effect is terribly small and would require a monstrous magnetic field to have any noticeable effect. This is how they make levitate a frog, it just requires 16 Tesla (the unit of magnetic intensity). The most powerful magnets have intensities of 1.4 Tesla so in order to reach higher intensities electromagnets are required.

in the span of negative infinity to positive infinity you can prove that all numbers occur zero times by the limit process. Take, for example, 3. In between 1 and 10, 3 will occur once (1/10), and for 1 to 100, 1/100. Using the limit, as x >> infinity, 3 occurs 0 times, since the fraction will always get smaller, indefinitely, as it approaches the value 0.
Other proofs like this can show that all numbers ate equal to 0 as well (though they hold far less tightly than the above, since it disproves all math, but math actually works).

When you treat numbers as events, it can be so. And there would be no math with nothing happening.

You’ve been using deodorant wrong your whole life. It is understandable, though, as putting on deodorant doesn’t looks like a complicated thing -and it isn’t, but the question is not how, rather when you should put it on. Probably you all put your deo on when you start your day, right? Well, that’s wrong.
An almost universally overlooked point is that the components of deodorants (chemicals and stuff) take time to have an effect on skin. Like, hours. This is why the right way to use deo, is to put it on before you go to sleep; this way it does its magic on your skin overnight, which is exactly what clinical grade deodorants isntruct their users to do. So in order to have fully effective deo in the morning, you must put it on the night before.

Sllly but alarming: the energy cost of bitcoin operations is on the rise and Bitcoins are consuming an incredibly large amount of energy. Due to the amount of computer power required, right now each Bitcoin transaction consumes 228 kwh (kilowatt hour), which equals the monthly consumption of a houselhold in a developed country. Each. Single. Transaction.
The global equivalent are some 24 twh (terawatt hour) per year, which is roughly the same energy as is consumed by Nigeria.
Using as model a mining facility powered by a coal plant, each new bitcoin mined is causing the emission of between 22 and 40 tons of CO2 (depending on the cost of cooling the farms and the hash/energy proficency of the farm boards).
And all this will just become worse and worse as more bitcoins are mined and traded.

Emulating video games on PC is legal in the United States but has a strict rule to make it fully legal. You are not allowed to distribute copyrighted material (code). This includes the BIOS of the console and the games for it. Though, you can flush the BIOS of a machine you purchased, and that is legal as long as you don’t give it to anyone else. What this means is, if you own the hardware and a disc, you can legally flush all BIOSes and data to any computer you own so long as there is no more than 1 copy at a time (cut and paste, don’t copy and paste). For those of you that live in other countries, look up the laws in your area about emulation before acting, if it says it is illegal… well… try not to get caught 
TL;DR
If you own any old console, or game, and live in the U.S., you are free to emulate them as you wish without legal issues.

Photocopier/Printer/Scanners have a little memory storage brain. Little, but able to store vast amounts of text or PDF file data . (Usually bit-hogging photos, audio, or video files never cross over into their busy little worlds). Therefore-- an old copier is a storehouse of saved and possibly confidential data. A couple of years ago, a big U.S. hospital chain took a million or so dollar fine for because the worn out copiers they sent back to Canon had Federally-protected (HIPAA) patients’ medical information on them.
Of course, guys these days who come in the truck to take the old ones out and put the new ones in have no idea what kind of world of hurt job they were getting into…
Googles offers a reward if a user is able to hack a Chromebook from within the guest session. In most cases of hacking, people are used to the hacker going to prison, but with google, if you show them what you did, they will pay you up to a standard limit of $100,000 US dollars. If you do not report it, however, it is then illegal and the reward you’d get is room and board in a jail cell (though I hear they now have Xbox in prison).
Although not offering a reward, the developers of the Linux kernel are looking for vulnerabilities and have openly asked for people to “hack” it, so that it can be made more secure.
In the end, not all forms of hacking are illegal, and others pay as well as the illegal ones without breaking any laws.
