One of the tasks that were assigned to the students is a challenge to build a rammed earth wall 1m in height and about the width of 2 bricks. The catch is that they have to add reinforcement made from natural resources like fibers from trees or human hair to increase the strength of the wall.
Based from internet research, the students made the formwork and use soils that is collected from the surrounding area. We manufactured the compaction device from metal rods that is embedded into concrete cubes and find out that they work perfectly.

We also discovered that the soil needs to be a bit wet to allow maximum compaction to be achieved. After allowing sufficient drying period the wall is tested for its strength based on the number of blows that it could withstand before crumbling.

Funny college jokes:
A young man studying in a college abroad sent this SMS to his father:
Dear dad, no mon, no fun, your son.
The father replied: Dear son, too bad, so sad, your dad.
