|What materials work the best in a sandbag for preventing a flood? |
The purpose of this experiment was to see what materials work the best in a sandbag for preventing a flood. Fine and coarse gravel, plant soil, and mulch are not usually put in sandbags to stop floods. Most people do not have a lot of sand that they can put in sandbags. That's why I'm doing this experiment, to see if fine and coarse gravel, soil, or mulch can have the same effect as sand.
