Answers
Answer:
Materials:
Plastic water bottle with a tight fitting lid, small nail, water
Procedure:
Put a small hole near the bottom of the water bottle using the nail. Be careful! Push it through or tap it in with a hammer
Put a small hole through the lid of the bottle with the nail (you will probably have to tap this through with a hammer, the plastic is thicker)
Fill the bottle to the top with water, holding your finger on the hole on the side of the bottle
Tighten the lid
Do this next part over a sink!
Cover the top with your thumb
Remove your finger from the side of the bottle and wait a second
Notice the water is not pouring out!
Take your thumb off the top now so the water pours out
Alternate putting your thumb back on the top of the lid hole and removing it
Explanation:
Did you notice the only time the water poured out of the bottle was when you weren’t covering the hole on the top? Isn’t that strange? There’s a hole there, why doesn’t the water come out? Shouldn’t gravity be pulling it down? There are different forces involved besides gravity. Air pressure is a strong force and it always acts in a certain way: High Pressure moves towards Low Pressure.
This basically means “more air” moves to “less air.” It is how wings cause flight, how spray paint cans works, how a plunger works, and much more! If there is a “vacuum” (a place with no air or less air than normal) then air will rush in to fill that void. So where does that happen in the Drip Drop Bottle?
