Ryan was a wealthy customer in a restaurant. Sitting in his table he asked a waiter for a juice glass, a dinner plate, water, a match, and a lemon wedge. The man poured enough onto the plate to cover it.

"If you can get the water on the plate into this glass without touching or moving this plate, I will give you $100," Ryan said, "You can use the match and the lemon to do this."

A few minutes later, the waiter walked away with $100 in his pocket.

How did the waiter get the water into the glass?
