Since jellyfish float in the water with their tentacles hanging down, you would say they put food into their mouth.
You would be lying on the surface tension of the water, with the pressure of your body evenly distributed across the water. The surface tension allows you to float effortlessly.
How much percent water are in a jellyfish? Answer The body of an adult jellyfish is made up of 94 to 98 percent water. Scroll down to related links and look for "Jellyfish - Wikipedia".
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
Beads float in water because they have a lower density than water. The buoyant force acting on the beads is greater than the force of gravity pulling them down, causing them to float on the surface of the water.
No, because it doesn't have enough density to do that.

Normally no. But if you carefully set the pin on some still water, yes it can 'float' on the water due to what's called surface tension. This is also what causes a small amount of water on a smooth surface to 'bead'. It's also what keeps water beetles on top of the water in ponds.
Surface tension is the property of a liquid that allows it to resist external forces. When surface tension is strong enough, it can support the weight of certain objects on its surface, causing them to float. This is because the surface tension creates a "skin" on the surface of the water that can support the object's weight without sinking.
A beach ball can float on water because it is less dense than the water, due to the air trapped inside the ball. The buoyant force exerted by the water on the beach ball is greater than the force of gravity pulling it down, allowing the ball to float on the surface of the water.
Expanded polystyrene will initially float on top of the water's surface, but if in permanent contact with water it has a tendency to absorb water very slowly (over a period of weeks) until it becomes waterlogged, at which time it may either float just at the surface or slowly sink.
No, because a hockey puck has a higher density than water. In some cases, objects with higher density than water can still float on the water, if they are small enough to avoid breaking the surface tension of the water. This is also the case if the object's mass is distributed across a large enough area, so you could float a penny on water if you put it down flat across the water, but it would not float if you dropped it in on its side. You also could not float that penny if you melted it down and made it into a sphere, for example.
