Can You Solve This Insane Riddle?

A man at a restaurant requests a juice glass, water, a lemon wedge, and a match. He offers the waiter a 100 dollar tip if he can get the water into the glass without touching or moving the plate.

• Juice glass with water • Lemon wedge • Match

The waiter accepts the challenge despite thinking the man is weird. The man successfully completes the task and the waiter walks home 100 dollars richer.

How did the waiter get the water into the glass without touching or moving the plate?

• One contestant thinks it requires sorcery, magic, or supernatural powers • Another contestant references junior high science class knowledge

• The lemon is for drinking water with lemon • The lemon wedge should be lit on fire • The match fire creates surface tension effects • Keeping air trapped inside the glass is important

Contestants struggle to determine the exact mechanism, with one asking if the fire helps and another admitting they can't figure it out.

One contestant calls the riddle bologna and laughs, expressing frustration with the unsolved puzzle.

• Place the lemon wedge in the center of the plate • Light the match and stick it in the lemon • Place the glass upside down over the lemon

As the match's flame uses up the oxygen in the glass, it creates a vacuum that sucks in the water where the glass meets the plate.

The waiter is able to get the water into the glass without moving the plate, completing the challenge and earning the tip.

The riddle is solved through oxygen depletion and vacuum pressure, not magic or surface tension.
