I felt that the Water/Salt Iced cube is a bit sandish, and the Normal Water Cube is Solid and has its own shape+ It's not Sandish Like the Water/Salt Cube and The Normal water cube Freezes Faster than the Water/salt Cube.

1- Pure water freezes faster than salt water, and upon research, I found that pure water freezes at 32 degrees Fahrenheit, while salt water may not freeze until it reaches minus 6 degrees Fahrenheit because salt disrupts the movement of particles that enter and leaves the solid.

2- Pure water was transparent before and after freezing, while salt water was not transparent before and after freezing.

result:  the pure water froze while the salty water didn’t freeze after one hour in the freezer.
