Explanation of scientific experiment

Today I saw one simple scientific experiment. Even though explanation was given , I could not hear it properly. I made my own logic behind the phenomena. A scientist took one glass long plate. He has spread a few drops of water over it and then kept a piece of paper on the wet surface. Now he placed a lighting candle in the middle and placed an empty glass beaker over it thus covering it completely. Now what happens next is interesting. Candle glows for a few seconds and then blown off. Now he lifted the entire glass plate and held it upside down ! No.,...no..... Nothing ( even the piece of paper ) fell down even though he made it upside down. WHY?????? This is entirely my logic. The candle was glowing inside the glass beaker. It will glow until there is a trace of air. When air becomes empty, candle will blew off. Now there is no air inside the beaker that means a vaccum is created. Now air present in atmosphere will rush to the vacuum area to occupy the space. It will exert such a force that the things which are in its way to vacuum area also will get attached to vacuum area. That's why when we make it upside down, things on ( piece of paper ) glass plate will not fall down. That is ATMOSPHERIC PRESSURE. .
