Lift a chair with atmospheric pressure! 🪝💪 #DrTatiana #science #shorts

A large piece of rubber with a hook attached to it acts like a giant suction cup. When Dr. Tatiana throws it on a heavy chair, there is little air left between the chair and the rubber, whereas the air pressure outside is about 15 pounds per square inch (or about a hundred thousand newtons per square meter). This is almost 1,500 pounds of force pressing down on a 10-inch by 10-inch piece of rubber, which is more than enough to hold the chair to the rubber when someone lifts it by the hook.

  7. I really admire people like this. I should've pursued something in the sciences.. i realised today i could've contributed more. However i am still relatively young at 28 years old.. i currently work in oil palm plantations.. its fulfilling.. its well paying but i always feel like i can do more.. i wonder what the future holds.. where my risk taking self will find myself..
