The sand puts weight on it and it makes in sink.
You can always buy them online, or at least at most tourist beaches. That's because water filled balls are common to use in the sand. (I would imagine)
I think you can but it would definatly go through a medal detector
Simply because of particle size. The size of the golf ball means there are a lot of large spaces created in between them, therefore leaving large holes. The sand is very fine, and it can be compacted to leave very little gaps.
If you stirred water and sand together, you would have a mixture of water and sand until the sand sinks to the bottom.

Sand would be plenty heavy enough but if you have a large umbrella and a small stand it would not hurt to fill with sand and then put water in after container is filled with sand. There is a little something called porosity, in this case the space between the granules of sand, the water would take up that space and add that much more weight to container. Hope this helps.
If you drop a ball in sand, the sand particles will absorb some of the ball's kinetic energy, causing the ball to slow down faster than if it were dropped on a hard surface. The ball will also create an indentation in the sand as it lands, displacing some of the grains.
Yes, pools are filled in, but I am not sure with sand. I would think that it would settle and after a bit on work well as a filler. I would call a pool company and ask the experts what to use.
When water is added to a beaker filled with sand, the volume of the mixture will increase, but not proportionately to the amount of water added. This is because the water fills the spaces between the sand particles, allowing for some of the water to displace the air pockets while still contributing to the overall volume. As a result, the final volume will be greater than the initial volume of the sand alone, but less than the sum of the individual volumes of sand and water.
the sea is made of water and sand. filled with amzing creatures.~sami~
The trenches were filled with water because when it rained if they didn't pile the sides up with sand and supported the sides would slip and make mud puddles at the bottom of the trench.
A simple filter would be suitable for separating sand and water. An alternative would be to evaporate the water, leaving the sand behind.
