Bamboozled Again! Odd Fast Food Cup Illusion Shakes the Web (VIDEOS)

Netizens racked their brains as they tried to debunk an optical illusion, which has been recently circulating on Twitter. A video, published to the network by @franco_713, shows what appears to be the same amount of soft drink being poured from a small cup into a medium-sized and then in a large one, and each time, the liquid fills the cups to the top edge.

The peculiar stunt quickly went viral, gathering thousands of likes and various reactions.

Confused by this strange experiment, several people even tried to repeat it, but quite obviously the miracle did not happen — the water from a smaller glass could not fill the bigger one.

Meanwhile, instead of disclosing his secret, the performer of the trick only added to the intrigue with a new video.

Some users claimed they had found the answer. They drew attention to the fact that the cups in the video were shown from the side so that the bottom couldn't be seen, which means they could have already been partially full or the trickster might have used "customized" cups with a false bottom.

However, in a follow-up video, @franco_713 demonstrated the bottom of the cups in more detail before repeating the same trick.
