They don't actually rise they tend to fall, when they rise it is the result of air currents blowing them upwards.

They float because the air inside the bubble weighs less than the air outside the bubble. All in all it all comes down to density. Because the bubble has less density than the air it floats.

Oil float over the water surface; use a decantation funnel for separation.


Can a needle float in soapy water?

Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension


Why is it that a bar of soap normally sinks but not if you put it in a soap case?

This is because the displacement of water to the the weight of the metal soap dish and soap is not equalized before the water reaches the top edges of the soap dish. If you had a deeper soap dish than it would most likely float. Also most likely the soap is 'stuck' to the dish so that is why when they sink it will not float on its own. Floating actually has to do with pressure rather than weight. For example a column of water 1 inch square and 1 foot tall, it weighs about 0.44 pounds depending on the temperature of the water so if you take a column of water 1 cm square by 1 meter tall, it weights about 100 grams. That means that a 1-foot-high column of water exerts 0.44 pounds per square inch [psi]. Similarly, a 1-meter-high column of water exerts 9,800Pa [pascals]. So it is the upward water pressure pushing on the bottom of the object that causes it to float. Each square inch (or square centimeter) of the object that is underwater has water pressure pushing it upward, and this combined pressure floats the object.
