Several ways are possible. 1) Freeze a rock at the bottom of an ice cube. When it is in the water, the ice cube will start to melt, then the rock drops out and the rest of the ice will float. 2) In a zip-loc baggie, put a weight (large washer or other piece of metal), take a square of paper towel and put a 1/2 tsp of baking soda in it and fold the paper towel over it and secure with paperclip. Put that in the baggie. Then pour in an ounce or so of vinegar and quickly close the baggie, squeezing out as much air as you can. Drop the bag into water and it will sink. As the vinegar soaks through the paper towel, it will react with the baking soda and create carbon dioxide, which fills the baggie and makes it float. Fun stuff!
An experiment you can try would be to fill a small glass or beaker with a clear carbonated substance ( i use 7up) then put a few raisins in the glass or beaker and then watch the raisins. this can also be done with spaghetti. you can look this experiment up on you tube its often called dancing raisins. this happens because the bubbles attract to to raisins and makes them float up. once they get to the top some of the bubbles come off making the raisins heavier. the raisins are naturally (only a little little bit) heavier than the original substance. (make sure the carbonated substance is fresh or it won't work!)
Objects float or sink based on a property called buoyancy. You can calculate whether or not an object will sink using Archimedes' principle, which essentially says that the weight of the displaced fluid must be equal to or greater than the weight of the object. This is dependant upon density (mass/volume).
If you want to make an object that normally sinks float, you have to change the density of the object or of the fluid.
For instance, if you increase the surface area of the object without increasing the mass, the object will float, as you can observe by the fact that metal ships can float.
That depends what object you want to float.
because th salt makes things float and George bush was the worst president
An object float in a liquid only when the density of the solid is lower than the density of the liquid.
you cannot make a floating and sinking bowling ball, it is highly impossible.
Less than that of the substance it is floating on.
Sinking or floating are determined by the density of the object.
not iron
To determine if an object will float in a substance, you look only at its density
If the object does not quite float in water, adding salt to the water might make the object float, yes.
etr
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
That depends what object you want to float.
Yes. If the object is in a lower gravitational pull, like the object is in the moon then it can float. But if it the object is in the Earth ,then the object will not float, also in water. But boats and ships are different cos it has a property or structure that make them float.
Archimedes' principles: -- An object in a fluid experiences an upward force equal to the weight of the displaced fluid. -- A sinking object displaces its volume. -- A floating object displaces its weight.
Well ehen they float in the water that means there dead.you dumney
Is this the density of a liquid or an object? If this is the density of a liquid and you want to make an object float, than the density of the object should be less than 2.7. If this is the density of an object you are trying to make float, than the density of the liquid should be greater than 2.7.
when a object float it has density
