A rat's ribs are hinged at the spine, enabling it to easily squeeze through the tightest spaces—like the pipes draining your toilet. And rats are great swimmers too; they can hold their breath for up to three minutes. See how quickly a rat can go from the city streets to your bathroom.

Why do you laugh when you’re tickled? Scientists at Humboldt University of Berlin are studying rats to try and solve the longstanding mystery. Given the right conditions, and enough back and belly tickling by a researcher, ratscan come to associate a researcher's cotton gloved hand with the sensation of being tickled. Tickling makes them “giggle, ” albeit in frequencies too high for human ears to hear. The rats develop a fondness for the human hands, chasing their scurrying fingers in circles. The scientists observe the rat ticklishness, and track how their brain processes the sensation, hoping to uncover clues about the laugh-inducing feeling.

2:46 Casting a Fire Ant Colony with Molten Aluminum (Cast #043)

Casting a Fire Ant Colony with Molten Aluminum (Cast #043)

An incredible metal structure is made by pouring molten aluminum into a fire ant colony. The resulting cast is huge, weighing 17.9 lbs. and reaching a depth of 18 inches.

See detailed pictures of the resulting cast on the Anthill Art website at http://www.anthillart.com/castings/043/

If you like my videos, then subscribe to my channel here. I'm also on twitter and instagram.

These are the red imported fire ants (RIFA) which are harmful to the environment and their nests are exterminated by the millions in the United States using poisons, gasoline and fire, boiling water, and very rarely molten aluminum.

From Wikipedia: "Researchers have also been experimenting with extreme temperature change to exterminate RIFAs [red imported fire ants], such as injecting liquid nitrogen or pressurized steam into RIFA nests. Besides using hot steam, pouring boiling water into ant mounds has been found effective in exterminating their nests."

I did a casual survey and found that I have at least 120 of these colonies within an area of approximately three acres. http://www.anthillart.com/info/fire-ant-survey/

10 Terrifying Creatures That Live After Death | Interesting Facts

Sorry, but i can't include footage with the headless snake in my video, here is the link:
https://youtu.be/T_8jywmeVPY

You may have noticed that, excepting the occasional zombie apocalypse, we humans tend to function best with our nervous systems intact and our brains, limbs and major organs all connected and happily communicating with each other.

Well, we feel it's our duty to inform you that not all creatures are quite so picky when it comes to the intactness of their bodies.
Hello and today we will talk about Terrifying Creatures That Keep Going After They're Dead

Headless Snakes
When faced with a venomous snake, most people's natural reaction would fall into one of three categories: fleeing, freezing on the spot or OH GOD OH GOD KILL IT CHOP OFF ITS EVIL POINTY HEAD.
While the latter course of action may seem like the surefire way to avoid getting bitten, it turns out that might not be the case.
What Makes This Abomination Possible?
The snake has heat-sensitive pits at either side of its face, which it uses to detect threats — and let's face it, if you're close enough for your body heat to be detected, you're close enough to be considered a threat.

Cockroaches
Cockroaches are infamous for their tenacity, and are often cited as the most likely survivors of a nuclear war. Some even claim that they can live without their heads. It turns out that these armchair exterminators are right. Headless roaches are capable of living for weeks.

Chickens
If you chop the head off a chicken, it can still run around for a few seconds. The animals can do this because a neural network in the spinal cord is pre-programmed to direct the muscles in various frequently used movement patterns such as running. Despite intense research into how the body, the brain and the nervous system works, scientists still do not have a clear picture of how nerve cells communicate to perform certain movements.

Octopus
Octopus tentacles still react up to an hour after being severed from their dead owner, and even try to pick up food and feed a phantom mouth.

Flatworms
Everyone knows the myth about earthworms: if you cut them in half, you get two worms. Nothing could be further from the truth, alas. However, if the earthworm is replaced by a flatworm, the two parts can survive these childish experiments. What’s more, be it skin, intestine or brain, the body part lost through cutting will simply grow again in a matter of days.

Frogs
Thanks to the "let's chop out its brain and see what the hell happens" approach to science taken by 19th century neurologist David Ferrier, we can tell you. A headed but brainless frog actually behaves very similarly to a frog with its gray matter perfectly intact: If you turn it upside down, it will right itself; if you pinch its feet, it will hop away; if you put it in water, it will swim to the side and climb out. And perhaps most disturbing of all, it will even croak contentedly if you stroke its back.ntinue to respond to external stimuli for an indefinite period.

Flies
Female fruit flies will live for several days after they have been decapitated. Such beheaded females assume an upright stance comparable to that of a normal fly and can and do engage in complex actions such as preening, flying and, under duress, walking.

Turtles
If you chop the head off a turtle, it can still swim. The turtle frequently uses swimming movements, so it makes sense for it to have a neural network in the spinal cord pre-programmed to perform swimming movements when the nerve cells are stimulated.

Salamanders
Salamanders can regrow entire limbs and regenerate parts of major organs, an ability that relies on their immune systems, research now shows.
A study of the axolotl, an aquatic salamander, reveals that immune cells called macrophages are critical in the early stages of regenerating lost limbs. Wiping out these cells permanently prevented regeneration and led to tissue scarring. The findings hint at possible strategies for tissue repair in humans.
