Lemon Experiment

Recently on biology class, we did an experiment to demonstrate the answer to a popular brainteaser, it goes like this:

''A man in a restaurant asked a waiter for a juice glass, a dinner plate, water, a match, and a lemon wedge. The man poured enough water 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," the man said. "You can use the match and 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?''

Well, the answer is quite simple, and here are some pictures taken from the experiment to follow the answer:

 Here is the first step of the process, pour the water on the plate and place the matches inside the lemon. Put the lemon over the plate.










Light the matches, and then put the glass face-down over the lemon. The fire will create a vaccuum effect, draining the water inside the glass, and then, you will get this!
