How do you make a submarine out of a 2 liter bottle that floats sinks then comes back to the surface when it is put into water without touching it?
The trick is to use Alka-Selter tablets and something to weight it down enough to ensure that the bottle will sink. It's an old trick used by submarine models I had when I was a kid, long before I served onboard real submarines.
Try this:
Use a length of copper tubing and duct-tape it to one side of the bottle as a ballast weight. Punch holes (nail size should be good enough) in the side where the ballast weight is. You'll need to leave the cap off or the water won't flow through the holes in the bottom.
To get it to rise again, you'll need several Alka-Selter tablets along with a surgical or cleaning glove, or alternatively, a long balloon. You'll have to break the tablets (don't crush them) to make them small enough to get through the neck of the bottle.
A balloon is a better choice. Put the tablets into the empty balloon, and then use a plastic tube (or something else) to ensure that the mouth of the balloon stays wide open. Put the balloon with the tablets into the bottle so that the mouth goes in first.
If you do it right, when you put the bottle in the water, the ballast weight should allow the water to come through the holes in bottom and the bottle neck. Eventually as it sinks, the water will enter the mouth of the balloon, and hit the Alka-Seltzer tablets. The gas from the tablets will fill the balloon and it should force it against the bottle neck and keep water from coming in. The gas should also force the water out of the holes in the bottom and float it to the surface again.
You can also try keeping the cap on and putting a hole in the opposite side of the bottle from the weight to let the air out as it sinks, but remember that when the balloon inflates it needs to close the whichever hole you use.
You might have to experiment with the right amount of weight and tablets, but you get the idea.

How do you crush a bottle without touching it?
With a straw or gloves
How can you put the egg inside the bottle without touching it?
To put an egg inside a bottle without touching it, you can create a vacuum by heating the air inside the bottle before placing the egg on top. As the air cools, it will contract, creating a lower pressure inside the bottle that will suck the egg inside.
How would you take a bottle without touching it?
You can use a piece of string or a cloth to create a loop around the bottle neck and lift it that way without touching it directly. Another option is to use a tool, such as tongs or chopsticks, to grasp the bottle securely without using your hands.
How do you fill a bottle without getting any air in it?
if your refering to a bottle you fill a giant bowl bigger than the bottle then you put the bottle under the surface then do the same to the cap whilevthe bottle is still under the liquesd and close it with both with the bottle and cap under the surface close it and tada!
How can I remove bottle labels effectively and without damaging the surface?
To remove bottle labels effectively without damaging the surface, you can soak the bottle in warm, soapy water to loosen the adhesive. Then, gently peel off the label using a plastic scraper or your fingers. If there is any residue left behind, you can use rubbing alcohol or a commercial adhesive remover to clean the surface.
An unopened bottle of water is taken out of the refrigerator and placed on a table After a while the bottle is covered with droplets of water What phase change has occurred?
Condensation has occurred, as the water vapor in the air has cooled down upon touching the cold surface of the water bottle, leading to the water vapor turning back into liquid water and forming droplets on the bottle.
Is it faster to cool beverages in ice only or ice water?
ice water, cause the cold temperature is touching more of the bottle or cans surface area so it cools down faster
What is klein bottle used for?
The Klein's bottle is a type of container which has no volume. You can navigate both the "interior" and "exterior" surface of a Klein's bottle without stopping or changing direction, only by going straight. "Int" and "Ext" are in quotes because a Klein's bottle technically has neither inside nor outside. A Klein's bottle is the 3d representation of a 4 dimensional shape, which is derived by folding a square's opposing edges together, to form a cylinder, then, with a half twist, folding the non-touching edges together. The result, viewed in 3d space, is a container which penetrates itself, but has no volume.
Why can you observe water droplets on the surface of a chilled bottle?
When a chilled bottle is taken out of the refrigerator, the air around it cools down rapidly, causing the moisture in the air to condense on the cold surface of the bottle. This forms water droplets that are visible on the surface of the bottle.
How does a bottle of ketchup shows both volume and surface area?
A bottle of ketchup shows neither volume not surface area. The only measurement on a bottle of ketchup is weight.
Can you hear a watch ticking in a airless bottle?
No, you would not be able to hear a watch ticking in an airless bottle because sound requires a medium, such as air, to travel through. Without air to transmit the sound waves, no vibrations from the watch ticking would be able to reach your ears.
