Hello. Today in science class, we had to create two tin foil boats out of the same amount of tinfoil and see how it impacted the buoyancy and stability of our boats. If they were both stable, we had to weigh them down with rubber cylinders.
Here is the video of my experiment: As you can see, the larger boat was much more buoyant because of how it stabilized the pressure, and it almost took the amount I had for both boats. Sadly, the smaller boat struggled to take on the amount it was supposed to. Its certainly interesting how the pressure changed the stability!
The formula used to determine pressure is P÷F/A (Pressure = Force÷Area) and due to the smaller area of the smaller boat, it would of undergone much more pressure. This explains why it sunk earlier than the larger boat.
I apologize for any background noise!
Have a nice day 🙂
