The mineral component of bone is comprised mostly of the calcium phosphate mineral hydroxyapatite which is embedded in the organic component type I collagen. When bone is exposed to a mildly acid environment the mineral component leaches out leaving only the pliable organic component. Vinegar is safe to use and does not destroy the protein scaffolding that gives bone it’s characteristic shape. This is a human fibula tied in a knot.

Did you know:
Apparently, bats can’t glide like birds can…
due to being bats and not having brittle birdlike bones but saying fuck you to gravity anyway and flying like the mammalian moth-munching MiGs of the (m)night they are…
Something I learned today, anyway, and given my source, it’s probably true…
and if not…well, now you’re thinking about bats.
It’s a beautiful home! By way of griseus:
This is an awesome man-made shell; made of glass by Robert DuGrenier, and was commissioned by the New Zealand Marine Studies Center and Aquarium so guests could see the inner workings of the hermit crab.

Just 23 miles west of Austin, Texas is a breathtaking natural oasis emerging out of the desert dust and scrub grass. More than a century ago, the natural dome that once concealed the entire grotto underground collapsed and created what is now called Hamilton Pool.
Hamilton Pool is a natural spring formed in the limestone bedrock and fed by an underground river, which also feeds the small tributaries and lush flora surrounding the pool. The abundant freshwater has allowed a diverse population of trees and vegetation to emerge surrounding the pool, forming a beautiful protected nature preserve.
The Historic and Haunted Ghost Town of Bodie
The old mining town of Bodie, California is America’s best preserved ghost town. Dating back to 1859, Bodie is literally frozen in time and looked after as an historic park. The town is both authentic and mysterious, with original fixtures, furniture, and personal items in the buildings left untouched since their residents abandoned them.
Bodie abounds with legends of the paranormal, but none more famous than the haunted Cain residence. The man of the house had an affair with their maid. After being publicly disgraced, the unfortunate maid took her own life and reportedly haunts the house.
The Cain house is open to the public and has provided accommodation for park rangers. People have reported ghostly apparitions and strange music. Staying overnight in the house, park rangers and their wives have experienced paranormal events such as hearing strange noises, being paralyzed in bed, and seeing items move by themselves.
The most frightening legend of Bodie is a mysterious curse that follows many visitors after they leave the town. Allegedly, Bodie’s ghosts serve as guardians to the town’s property, casting bad luck and misfortune to souvenir hunters who take anything with them.
Each month, Bodie’s park rangers receive objects and letters from people who admit to taking items and beg the rangers to put them back. The letters tell tales of horrible incidents such as mysterious illnesses, car accidents, and even death. The rangers frequently speak of these accounts and assure the senders that the objects are always returned to their original places.
The Amazing Underwater Forest of Lake Kaindy
What makes Lake Kaindy truly remarkable is that it contains an underwater forest. Visible on the lakes surface are the tall, dried-out tops of submerged Spruce trees that rise above the water’s surface like the masts of sunken ships. They are the only sign of the amazing frozen forest below the water’s surface.
The water is so cold (even in summer the temperature does not exceed 6 degrees) that the pine needles remain on the trees, even after a hundred years of being submerged. During the winter, the lake freezes and becomes a popular spot for ice diving.
The lake is 400 meters long and is located in Kazakhstan’s portion of the Tian Shan Mountains, about 129 km from the city of Almaty. The lake was created after an earthquake in 1911 triggered a large landslide blocking the gorge and forming a natural dam.
