Punto cieco

Close your left eye and look at the line of the left that is perpendicular to the line across the image. Move your screen back and forth until the ball on the right is no longer visible. This is your blind spot https://t.co/KMDU2foftp [maximize the picture first] pic.twitter.com/PqMfhmFWEl

Pericolo?

These people are not in danger. What is coming down from the left is just the Moon, far in the distance. Luna appears so large here because she is being photographed through a telescopic lens https://t.co/V3mFjHBOPQ pic.twitter.com/a8nnX4AH8u

Metasepia pfefferi

It looks like a little hippopotamus that can change its colour... A hypnopotamus? It's a Metasepia pfefferi, or Pfeffer's flamboyant cuttlefish, one of the most intriguing species of cephalopods [source of the gif: https://t.co/2hxvYHbti6] pic.twitter.com/UQThl6bRQH

Gomboddo anche nel ping-pong

Magnus effect, can send even a ping-pong ball curving up, down, left, or right – always at a right angle to the direction of motion – depending on which way the ball is spun. This is a remarkable example https://t.co/8fafrDQiLF pic.twitter.com/KWe0ETDU9O

Alt-tombolo

Artist Petros Vrellis' “A New Way to Knit” lives up to its name. What he’s done is to take the traditional circular loom, some black thread, and toss some computing at it: the end result of following the computer’s instructions is a greyscale portrait https://t.co/dKQajUKJWk pic.twitter.com/G9g9aDbLjz

C'è o no?

Scroll up and down and you will see circle appearing near the center of the image: it's an optical illusion quite similar to the 'shake your head to see the picture' with a kind of Moiré effect in it https://t.co/bDRgMKaagt pic.twitter.com/X1VePbTCVk
