Buoyancy Shoes By Krunch

            There will be a design of using the buoyancy’s theory to make a buoyancy shoes that can floating on the surface of water and able to accommodate 80kg of weight when walking on the water’s surface. And for this Project for calculate the buoyant force we used a Common Equation:


FB = Weight
ρgV = ρobjectgVobject

Few factors are affected to the stability of the buoyancy shoes. They are the shape of floating object use, material of floating object use, volume of floating object use and the density of the fluid.
Objective
1.      To design a buoyancy shoes that able to accommodate 80 kg of weight when walking
on water.
2.      For better understanding about the concept buoyancy and its application in any fluid.
3.      To stimulate the spirit of team work and the leadership during the process of project.
4.      To innovate a creativity product that can be contribute to the social in future.
5.      To stimulate the creative knowledge of the students.
 Theory

1.      Buoyancy is an upward acting force exerted by a fluid, that opposes an object's weight.
2.      By Archimedes, a Greek mathematician, in what is known as Archimedes Principle
3.      We can see that whether an object floats or sinks
4.      The buoyant force is equal to the weight of the replaced liquid or gas
5.      The weight of the displaced fluid is directly proportional to the volume of the displaced fluid
  
Methodology
The 2004 Edinburgh International Science Festival ran a competition called Walking on Water. The picture above was one of the design of the group.

Initial Design
Firstly, we collect the information about the concept of buoyant force through reference book and internet. Next, research had been done to choose the best material to design the buoyancy shoes. Cork has been chosen as our material due to the low density

Calculation
 

Final Design
            The final design is the improvement of the initial design. After our meeting, we had decide to change the design and the shape of our buoyancy shoe. The final design will help us to slide easily and the volume had been increased so as the buoyancy force. On the other hand, the material remain the same because cork have low density and it can float on water. 

Limitation
Can support weight up to 50kg, thus the total weight that the shoes can support is 100kg, If the weight is more than 100kg:The shoes may sink. Besides that, the shoes we design is in rectangular shape Unfortunately, we can’t walk as normal on the water. We have to slide with small step to make sure there are no other force acting on the shoes besides our weight so that the shoes does not sink.


Conclusion
            Thanks for all the reader and followers hope this blog can give to all reader some knowledge about buoyancy Shoes. Thank you.
