Aim:
I want to know how to make a boat that can hold as much weight as possible before sinking.
Research:
Method:
Equipment
- One 30cm x 30cm square of Tin Foil
- Bucket of water
- Weights (we will use rubber bungs)
Instructions:
- Get your equipment.
- Fold your foil into a boat by following the instructions in the video.
- Float the boat in water.
- Slowly add weight until the boat sinks.
Results:
Discussion:
Buoyancy is the force on an object making the object rise or move forward. Large ships are less dense than water. Your foil boat floats as a result. Your foil was folded into a form with a high volume that absorbs a lot of water. Because of this, the aluminium foil on your boat weighs significantly less than the water it moves.
The upward force on the boat immersed in water is equal to the weight of the water displace by the boat, this is call Archimedes Principle.
