When the glass is lifted out of the water, air rushes to the top of the glass and forces the water to fall out. This pressure is enough to overcome the force of gravity on the water in the glass and the water stays in the glass instead of falling back into the bowl. It is pushing down on the water around the glass. While the glass is being lifted out of the water, gravity is trying to pull the water to the Earth and out of the glass.Īir pressure is always at work, as well, constantly pushing on matter. The same is happening with the water in the glass. Gravity is always pulling matter to the Earth. There are two forces at play in this experiment – gravity and air pressure. What happens to the water in the glass? What Happened? Lift the glass above the surface of the water. Note: The glass in the photo has a thick, clear bottom, so it appears there is air in the glass, but there is not. Notice that the water is still in the glass and isn’t falling back into the bowl.
#Defying gravity full
The glass should be full of water with no air.Ĭarefully lift the glass until the top of the glass is just below the surface of the water. While keeping the glass under the water as much as possible, turn the glass upside down in the bowl. Our glass was sticking out of the water a tiny bit and the experiment worked just fine. Next, place a small glass in the bowl of water so that the glass fills with water. We used a large, glass mixing bowl and placed it on the kitchen counter so spilling water wouldn’t be a big deal. The color will make it easier to see the experiment. To set up this experiment, fill your large bowl with water and add a bit of food coloring and mix it well.

Can something that normally falls to the ground simply not fall? Let’s try with this gravity experiment. It is why objects fall to the ground when dropped and why when you jump into the air, you come right back down. Is there a way to defy gravity Can something that normally falls to the ground simply not fall Let’s try with this gravity experiment. Gravity is the force that pulls matter toward the Earth. Gravity is the force that pulls matter toward the Earth. If you have a glass of water and you turn it upside down, what happens? The water falls out of the glass and onto the floor. When you drop an object from your hand, what happens to that object? It falls to to the ground.
