You cannot crack your knuckles. The sound it makes is due to the gasses that are released when you put pressure on them. When joints are stretched, the pockets of gas between the joints are released.
100 Mind-Blowing Stretched Facts
Scraunched is the longest word with one syllable. In the English language, ‘scraunched’ is the longest one-syllable word. Other examples are screeched, schlepped, scratched, scrounged, scrunched, and stretched.
Slinkies are 82 feet long. Fully stretched out, Slinkies can reach up to 82 feet – or as long as 14 average-sized people.
The length of the circulatory system is almost 60,000 miles According to the Franklin Institute, if all the veins, arteries, and capillaries in a child’s body were stretched out flat, they would span more than 60,000 miles. Our bodies house around 100,000 miles of blood vessels by the time we reach maturity. That is only one of the astounding facts that seem fabricated but it’s true.
A person’s arm span (the length of their arms stretched out) is about equal to their height.
Earth’s magnetic pole is creeping westward. Unlike our geographic North Pole, which is in a fixed location, Earth’s magnetic north wanders. Until the early 1990s, the magnetic North Pole was known to lie some 1600 km south of true north, in Canada. Yet scientists realised that the location of the magnetic north wasn’t fixed and was drifting at a rate of 15 km a year. Since the 1990s, however, the drift of Earth’s magnetic pole has turned into more of a sprint. Its present speed is around 50-60 km a year and is making a dash towards Siberia at a pace not seen before. Why? Scientists studying the drift of Earth’s magnetic north pole, using data from ESA’s Swarm mission, have pinpointed a change in the circulation pattern of magnetic blobs deep below Earth’s surface. They learned a change in the flow underneath Canada has caused a patch of magnetic field at the edge of Earth’s core, deep within the Earth, to be stretched out. This has weakened the Canadian patch and resulted in the pole shifting towards Siberia.
