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.

Who understood her after watching the second time?
what an annoying teacher.
Rj ❤
Her specs 😮
She could talk normally
Could you engineer that to be vacuumable and take all the air out to get closer to the 1500 nurmber?
She is a pro at physics
She's fantastic. If you want others to find something interesting or awesome, you have to actually find it awesome and cool yourself. Be childlike, be excited, exaggerate, show it off like you show off a story or music you love, and the passion you show will resonate.
I love when she shouts at the stool about what she wants to do 😂.
I want this teacher for wisdom
The editing on this video is mad! Not 1 pause to take in the information. Just frantic!
