!!Atmosphere Pressure Experiment!!! Crazy Chris shows us that the atmosphere has enough pressure that it can push hard enough on water! Objective: To understand atmospheric pressure. Materials Needed: ~ plate ~ glass jar ~ candle ~ water ~ lighter or match Step 1) pour some water into the plate. Step 2) light the candle with the ligher or a match and place it in the center of the plate. Step 3) Place the glass jar over the candle and watch. HOW DOES IT WORK: The reaons the water rises upint othe jar, is because of atmopheric pressure. When you put the lit candle in the jar, the heat causes the air to expand which is why the rapidly. Once the fire has used up all the oxogen in the jar the flame goes out and air inside quickly cools loosing pressure. The higher outside air pressure pushes on the water and the water goes up into the jar. Air is made of molecules of gas and these gas molecules are held to the earth by earths gravity. Which causes these molecules to push down on everytihng creating pressure. The lower you are on earth the more air molecules there are above you and the higher the pressure will be. The higher up in the atmosphere you go the less air molecules and the less pressure there will be. Wich is why air planes pressureize thier cabins to the ground pressure and is why water boils faster in the moutains. !!Atmosphere Pressure!!
