In summary, the strange sand bag works by utilizing a unique combination of materials and design to absorb and disperse impact energy. This allows it to effectively protect against various threats, such as explosions and projectiles, without adding significant weight or bulk. The bag also has the ability to mold and conform to its surroundings, making it versatile and adaptable for different environments. Overall, the strange sand bag is a highly effective and efficient solution for providing protection in a variety of situations.

According to its datasheet, it contains cross-linked polyacrylamide, which is a material that will soak up a lot of water, expanding in the process. So, the answer is "just add water".

I guess that means you probably have to get it wet BEFORE the storm arrives, otherwise it will be too light and will blow away.

Also, I'd expect that even when it's wet, its density wouldn't be as high as a normal sand bag, so it might get washed away more easily.

thanks for the explanation, so it's not trustful at 100%
 

FAQ: How does this strange sand bag work?

How does the sand bag stay in place?

The sand bag stays in place due to the force of gravity. As the sand inside the bag is pulled downward by gravity, it creates a stable base that prevents the bag from moving.

How does the sand bag absorb water?

The sand bag is made of a material that is highly absorbent, such as burlap or polypropylene. When water comes into contact with the bag, it is absorbed into the material, causing the sand to become heavier and more compact.

How does the sand bag prevent flooding?

When placed in strategic locations, sand bags can create barriers that redirect the flow of water and prevent it from reaching certain areas. The weight and absorbency of the sand also helps to slow down the movement of water.

How does the sand bag protect against erosion?

Sand bags can be used to create erosion control structures, such as dikes or revetments, which help to stabilize shorelines and prevent erosion. The sand inside the bags absorbs the impact of waves and helps to dissipate their energy.

How do you dispose of a used sand bag?

The best way to dispose of a used sand bag is to remove the sand and then recycle or properly dispose of the bag itself. If the sand is contaminated with chemicals or other hazardous materials, it should be disposed of according to local regulations.
