Gravity Tricks

While standing up, bend over and hold your toes with your hands, keeping your knees

slightly bent. Try to jump forward in this position without removing your hands from your toes while

you are jumping. Can you do it? Bet you can't!

The Impossible Leap:

In this position, you can jump backwards from one end of the room to the other, but you won't be able to jump forward even a single leap! When we jump, we first shift our center of gravity in the direction we want to jump, and then we move our support base in the same direction to regain our balance. When you are holding onto your toes, jumping backwards is not a problem because you can use your heels. But to jump forward, you would have to use your toes... and your fingers are in the way

The Science:

Sit in a straight-back armless chair, keeping your back

against the back of the chair and your feet flat on the floor.

Fold your arms across your chest. Keeping your feet flat and your back straight, try to stand

up. Are you glued to your chair?

Super Glue Chair

In this sitting position, the center of gravity is at the base of your spine. By trying to stand up with your back straight, you prevent the center of gravity from moving to a position above your feet, which would be necessary to stand up. Therefore, you remain glued to your chair

Granules: convection from inside the sun causes the photosphere to be subdivided into 1000-2000km cells that look like rice grains or kernels of corn.
