You can make a campsite video advertisement using a watertight container.
Watertight means that when the lid is sealed, water cannot get into or out of the container.
To make a lifeboat out of a paper cup, start by reinforcing the cup with tape to ensure it holds its shape and is watertight. Next, create a small sail using a piece of paper attached to a toothpick or stick, and insert it into the cup for stability. Finally, test the boat by placing it in water; it should float and potentially carry small objects. Adjust the design as needed for better buoyancy or stability.

No. Most cars aren't even approximately watertight. There have been "amphibious" cars that are watertight on the bottom, to allow them to float, but even on these the door seals usually aren't completely watertight, and there's almost always ventilation of the passenger compartment somehow ... it may float, but submerge it and it would fill up with water.
