Today we learned more about the HUMAN BODY! We learned a little more about bones and joints (including using a straw to see why long bones don’t bend but small bones stacked on top of one another like the vertebrae bend easily). Then we studied a little bit about how muscles work to help bend joints (like how hamstrings and quadriceps move the knee). Then we made a few experiments to show how lungs work! We made our own version of how the diaphragm helps with breathing. And we used water displacement to show how much air was in our lungs. Pretty cool, huh?! #sciencesunday#stemlearning#girlsinstem#humanbody#musclesandjoints#breatheingoodvibes#stemmingwiththecardwells
Here's our tallest man living record holder Sultan Kösen at a recent Guinness World Records event at Kashirskaya Plaza in Moscow, comparing hands with Fiona from our team. The amazing Sultan, who hails from Turkey, also holds the record for the largest hands on a living person - 28.5 cm (11.22 in) from the wrist to the tip of the middle finger. Joining Sultan and our records team at the event was shortest married couple Paulo Gabriel da Silva Barros and Katyucia Lie Hoshino from Brazil. Swipe right for more photos!
Oddly satisfying video of a procedure called sclerotherapy!
Sclerotherapy is a medical procedure whereby a chemical, the sclerosant, is injected into a vein to entirely obliterate it. It is commonly mixed with air to make a foam like substance that tend to stay in the vessel more firmly. The sclerosant damages the innermost lining of the vessel, resulting in a clot that blocks the blood circulation in the vein.
To prevent back-flow, most veins have valves that only allow blood only to flow in the direction of the heart. When these valves become incompetent, veins become enlarged and bulging (varicose). Smaller veins that feed these varicose veins can also become enlarged and appear as red or blue spider veins in the skin.
Varicose veins can lead to a chronic swelling condition of the leg called venous insufficiency. Venous insufficiency predisposes a person to blood clots and skin ulceration. The destruction of these types of veins can be desirable both medically and cosmetically.

One out of six patients lost 21.3 grams when he died. As result MacDougall determined the weight of the human soul to be 21.3 grams but also stated that the experiment would have to be repeated many more times. Other scientists were sceptic due to the experiment being flawed and the number of the subjects being rather small. But despite its rejection, MacDougall's research popularized the concept that the soul has weight.
Do you think there is a soul and that it has a weight? I would love to read your thoughts on this in the comments below. Also don't forget to follow me, @schauderhaft_ for more interesting facts!
