Objects float or sink because of their density.
An example of an object with low density is a sponge, as it has loads of air bubbles in it, and will float.
An example of an object with high density is a brick. This is because the brick doesn't have any air trapped in it, it is "packed in", and is more dense than water, therefore it will sink.

∙ 12y agoSome types of sponges float, and others sink.
If the sponge soaks up water, then sinks, it means that the sponge material is actually denser than water, and the sponge was floating due to the air spaces in it. Once all of the air spaces fill up with water, its average density goes from less than water to greater than water, and it sinks.

∙ 15y agoWhen water replaces the air in a sponge, it can no longer float. The air is what causes it to float.
Wiki User
∙ 14y agoBecause the sponge is less dense than the water

∙ 11y agosink, because it absorbs water then weighs to much for the water to hold then sinks.

I have a science experiment to do. How do you do a sponge absorbency project?
Oh that's quite simple. Find a sponge and get a bowl. Put the sponge in the water and explain how the pores in the sponge suck in the water as you put pressure on it. As you squeeze it explain that the pores release the water through them.
What is the tool in science that if you put in water it doesn't sink and in olive oil it does?
When you put a science tool in water it doesn't sink and in olive oil it does sink
Does the shape of a sponge affect how much water it will absorb?
yes because all sponges have pores and certain materiel does not have many pores.For example a piece of foil compared to a sponge the foil is not going.
Where does water enter a sponge through?
tiny "whips" on the cells inside a sponge draw water in through the pores of thesponge. Food is then removed from the water before it leaves through the opening at the top of the sponge .
Can cotton absorb water quickly?
cotton does soak up a little water. It soaks up water cauzz it has litttle air holes just like the sponge...but it is not made of the same material as sponge soo it wont soak up as much as the sponge
Give some exampleof materials that sink and float in water?
rocks metal eggs dirt or sand all sink some woods sponge plastic aluminum cans all float
How is floating related in density of material?
If an object is less dense than the substance it is placed in, it will float. For example, a sponge is less dense than water, so will float. However, if you squeeze the sponge underwater so that it has no air left in it, it will sink, as it will be the same density as the water.
How does water enter the body of a sponge?
When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
How does sponge hold water?
a sponge holds water because of its holes
What is full of holes but can carry water?
A sponge is something that has allot of holes, but can still hold/soak up water.
What part of the sponge does water flow in?
The part of the sponge the water flows in is the hole.
Does the size of the sponge affect the amount of water absorbed?
The size of a sponge does affect the amount of water absorbed. The bigger the sponge the more water absorbed.
What holds water but is full of hole?
A sponge
If a sponge can be out of water why cant sponge bob?
He has gone out of the water before and been fine.
Which will sink water or maple syrup?
Maple syrup will sink but water is unable to sink because it is water.
Why do you sink in water?
the water sink is not solid and liquid
What are the object that sink in water?
object that sink in water
