no
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
A small piece of feces is mixed with the fecal float solution in a special container. Then the container is filled with solution until it a meniscus forms at the top. Set a coverslip on that and then wait 10 - 15 minutes.
Cullets doesn't float on water.
Helium
No, the baby never filled them with air from their first breath, therefore they are fluid filled...and won't float.
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
You can use a milk container filled with water to weight it down so it doesn't float. You can put one or two bricks in the tank.
It depends if the carton is full or not. If the carton is empty, then it will float. If their is milk in the container, then it won't float.
markers float because they are less weight. and it doesnt have metle on it.
Whether or not you float has nothing to do with vacuum. You float because you are too far away from the earth (or other massive objects) for their gravity to have any noticeable effect on you. It just so happens that this occurs in space where natural vacuum may be found.
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
You can determine if a rock can float by comparing its density to the density of water. If the rock is denser than water, it will sink. If the rock is less dense than water, it will float. This can be tested by placing the rock in a container filled with water and observing its behavior.
