Why does the same piece of foil float or sink?
The same piece of foil can float or sink depending on its shape and how it is positioned in the water. If the foil is shaped to trap air, it will float. If the foil is crumpled or folded so it doesn't trap air, it will sink.
Five ways how to make a plasticine float?
Increase its volume by adding more plasticine. Shape it into a hollow, buoyant structure like a boat or raft. Use a light material, like a small piece of foam, to help it float. Mold the plasticine into a ball shape, which can displace water and float. Create an air pocket within the plasticine to increase its buoyancy.
Will copper float in fresh water?
Copper is more dense than water so a piece of copper will sink and not float in fresh water. However if the copper is formed into a container like shape similar to that of a boat it will stay on top of the water. For a better understanding of why, look up Archimedes Principle.
Which is a better insulator wood or styrofoam?
Styrofoam is a better insulator than wood. This is because styrofoam has a lower thermal conductivity, meaning it's better at resisting the flow of heat. Additionally, styrofoam is lightweight and easy to shape, making it a popular choice for insulation in buildings.
How much Styrofoam per pound of weight?
The volume and weight of Styrofoam can vary widely based on its density and form. On average, one pound of Styrofoam may fill around 0.5-1 cubic foot of space. However, this can change based on factors like the shape and compression of the Styrofoam.
Why does a coin sink while a piece of styrofoam of a similar shape and size floats?
Because a coin is more dense than water, while styrofoam is not.
Why does a coin sink in water while a piece of Styrofoam of a similar size and shape floats?
Coins are denser than water. Styrofoam is less dense than water.

How do you build a strong tower made out of toothpicks and white glue?
Buy pieces of styrofoam. Then, you stick the base in styrofoam. Next, you measure the length of the first piece and the length of the shape of the toothpicks. You may put some vertical on the horizontal toothpicks. Cut off the top of the toothpicks, and put glue on them. If you just poke the next piece of the styrofoam on, you wouldn't be using the glue. Make sure the length of the styrofoam is slightly bigger than the shape of the toothpicks. Glue the styrofoam on. Lastly, do it over and over again until reached height desired. You will need • pieces of styrofoam • Over 100 pieces of toothpicks • Elmer's Glue-All glue
How can you make a piece of iron metal float?
if u made the piece ofmetal hollow it can float unless its density is larger than the water densityANSWER:If you make it displace more water than what makes it sink, it will float, as in a ships hull. If you make pontoons out of it, it will float. If you make an enclosed shape that contains enough air, it will float. There should be less density in the item than the water.

How do you make a styrofoam wig. It's for cosplay and I see dragqueens with styrofoam moulded wigs and I need to learn to make them. Any ideas or pointers. I know nothing as of yet. Help?
I have never heard that idea. It must be unique. I would say take a large piece of styrofoam and cut it into the shape you want, but they do sell gelled wigs that work well too.
Do aluminum can peices sink or float?
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.
Why are styrofoam peanuts called peanuts?
They are called peanuts because of their similar shape and size to actual peanuts. The small, lightweight, and cushioning properties of the styrofoam peanuts make them an ideal material for packaging and shipping fragile items.

Why are the little styrofoam pieces in a package called peanuts?
The term "peanuts" for the styrofoam pieces in a package was coined because of their small size and shape, resembling actual peanuts. These pieces are used for cushioning and protection of items during shipping and hence help prevent damage.
