If you are making a cell model you can either use plastic bags or balloons filled with water.
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
The aluminum foil is less dense than the water which makesit float. Aluminum foil is not less dense than water. It is more dense. The reason that aluminum foil floats is that the surface tension of the water will hold the sheet of foil. If you still think that the aluminum foil is less dense than water, try floating a roll of foil in a bucket.
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.
If you are making a cell model you can either use plastic bags or balloons filled with water.
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
No they sink to the bottom because they hold no air.
A can can hold approximately 16 fluid ounces of water and still float in water. Beyond this amount, the can would likely sink due to the weight of the water exceeding the buoyant force that keeps it afloat.
You just smash it.
the modern iron has a small "shell" to hold the water in it now if its empty and is in water it may float from the air inside the iron
