How much dish soap do I need to sink a boat?

1 Answer

Answer :

answer:Spiders are about as heavy as the amount of water they displace. So if they tried to float, they would be mostly under water and unable to breathe. The ones that walk on water do so by carefully placing their feet down so as not to puncture the surface tension of the water, and keeping enough feet in contact with the water surface at all times so that the surface tension is sufficient to support their relatively low body weight. Since soap reduces the surface tension of water (that’s what makes it work in cleaning, it lets the water get to the dirt) soap makes things relying on surface tension unable to use that principle to stay above the surface of the water. They sink to wherever the flotation principle below would establish their waterline. If they are heavier than the amount of water they displace, they go to the bottom. Boats operate on an entirely different principle from surface tension, the principle of flotation. Even ones made with steel hulls have a great deal of air inside their hulls, so as they sink down in the water, the total weight of water displaced by the hull eventually matches exactly what the boat and its contents weighs. Soap reducing water’s surface tension has zero effect on the flotation principle. If you want to sink a ship with dish soap, fill its entire hull and all the cabin space with the soap and down the ship would go.
