Why do the water in a drinking straw does not drip out when you press the top of the straw with your thumb or finger tip?
When you press the top of the straw with your thumb or finger tip, the pressure you apply traps air inside the straw, preventing the water from dripping out. The pressure you exert keeps the water forced inside the straw despite gravity trying to pull it down.
Why would the water in your drinking straw not drip out when you press the top of the straw?
When you press the top of the straw, you create an area of low pressure inside the straw. The atmospheric pressure outside the straw then pushes the water up into the straw, preventing it from spilling out. This balance of pressures keeps the water inside the straw when you press the top.
Why does a straw hold water if you put your thumb over top of it?
When a thumb is placed over the hole in the top of the straw, it seals the entry way for air. When the straw is pulled out of the water, it is to be noted that a drop or two of water falls out of the bottom but no more falls. This is because when the water droplets fall, this creates more space in the air pocket in the top part of the straw. WIth more space the pressure decrease in the air pocket. In addition, gravity is working on the water inside the straw, but these two forces do not outweigh the force of atmospheric pressure outside, as a result, the water stays within the staw.
How can we reduce the negative impact on our teeth when drinking soda or water through a straw?
Using a straw when drinking soda or water can help reduce the negative impact on teeth by minimizing direct contact with the teeth, which can help prevent erosion and decay.
Why does a straw bend when it meets water?
When a straw meets water, the water molecules are attracted to the straw due to the force of surface tension. This attraction pulls the water up the sides of the straw, causing it to bend as it follows the shape of the straw.
The water in a drinking straw does not drip out when you press the top of the straw with your thumb or finger tip?
there is no air
Why the water in a drinking straw does not drip out when you press the top of the straw with your thumb of finger tip?
Because under your thumb, inside the straw, there is now a vacuum which keeps the water in.

How do you operate a water filter straw to purify water for drinking?
You can put the straw into the water and then suck, the water will come out filtered.
The water in a drinking straw does not drip out when you press te top of the straw with your thumb or finger tip?
It's a matter of air pressure that acts on the water. When the straw is uncovered, there are two forces acting on the water inside. There is gravity, pulling the water down, and air pressure. The pressure is about the same on both ends of the straw, but on the top of the straw, the pressure pushes the water downward, and on the bottom of the straw, the pressure pushes upward. Both of the pressures are the same, so the net force is just the force of gravity pulling the water down and out of the straw. When you cover the top of the straw, you block the air from pushing down on the water. In this case, the only forces on the water are the air pressure pushing up, and gravity pulling down. However, the air pressure is a greater force than gravity, and keeps the water in the straw despite gravity's pull.
Is drinking out of a straw healthier for you?
No. It's the same as drinking right from the cup. Unless your out in the wilderness and you don't have clean water, you can get straws that filter your water.

What would happen if you put a drinking straw into a half-filled cup of water?
The straw would displace the water in the cup, causing the water level inside the straw to rise above the water level in the cup due to atmospheric pressure. The water would remain at a stable height as long as the straw remains in the cup.
Do straw float in a glass of water?
Yes, plastic drinking straws will float in water.
