May 10, 2007nbsp018332Finer sand may weigh more because you can pack a lot more of the fine particles of sand in a particular area than bigger grains. But if you try.
Rocks are large enough that they won39t leak through the screw cap or even through cracks in an older bag. They also make a pleasant noise when the bag rattles after a particularly effective punch or kick. However, rocks can be harder to load into or out of the reservoir because they don39t flow as well as water does. Using pea gravel instead of irregular stones can help minimize that disadvantage.
Sand splits the difference between water and rock. It flows into the reservoir easily if dry, but is less likely to leak when the bag is tipped and won39t cause condensation. The chief problem with sand besides the hassle of going to a landscaping supply shop to get some is its tendency to settle. If moisture gets inside the reservoir, sand can set into a form not much softer than concrete. This can make it very difficult to empty your bag to move to a new location.
If you39re a boxer, the benefit of putting in time on a bag is obvious The more you practice a skill, the better you get at it, and the more punches you throw, the more naturally they39ll come.

So last night my husband and his buddies wanted to mess around with the punching bag on a stand and usually you can fill those with water or sand to weight them down so it doesnx27t come back and hit you or fall over when you hit it. Well then him, his two buddies, me, and the buddiesx27 wives all got into a discusssion about which weighs more, sand or water. We are split three to three, and canx27t find the answer anywhere. Can anyone help.
Depends on the volume. Also the kind of sand. A pound of one thing weighs the same as a pound of something else.
It depends. Sand is denser as it sinks in water. HOWEVER, a bag of water will not have any spaces in between as there are spaces in between sand. And each sand particle is different in size and density as well. So youx27d really have to weigh it. scoop a cup of that sand and use it as the general sample for the overall weight of the sand. then measure the weight for the cup of water.
In almost all cases a gallon of sand would weigh more. Based on the relative density given in one of the other answers 1.44 if you are trying to work out how much heavier the tank would be with a given amount of water you would also need to know how much water will be held by a gallon of sand holding space between sand granules. Assuming a gallon of sand could also hold 0.25g of water the actual weight of sand would be 1.69 times the weight of just water.
Tink Youx27ve ridiculed people for saying a gallon weighs a gallon despite it being a measure of volume, not weight, yet you have said a lb of sand weighs more than a lb of water. A lb of anything weighs the same because it always weighs a lb.
Wow, how dumb some answers are. First, a gallon is a measure of volume,.not mass. Therefore, the more dense an object is, the more it will weigh in a certain volume. A gallon of water is roughly 8 pounds. Ix27ve never weighed a gallon of sand, but it feels more dense and therefore should weigh more.
Feb 25, 2009nbsp018332To answer what weighs more a pound of anything is a pound. Now a pound of concrete may have less volume than a pound of sand but they are both still a pound. If you want to make your gallon as heavy as possible I would fill it with pennies. You probably wont be able to lift it if you do.
