1. The problem statement, all variables and given/known data Analyse the physical world around you in terms of Circular Motion/ Energy/ Momentum / Pressure/ Buoyancy/ Bernoulli's Equation. Choose one aspect you would like to investigate further. 2. Relevant equations e.g. why some potatoes float and other do not 3. The attempt at a solution I tried using candles due to not having potatoes. I noticed that the candles float on the side with the greatest area. In other words, a shorter cylindrical candle floats on its 'base' while several identical candles combined floated on their side. If this is a bit too advanced ( never covered centre of buoyancy and surface area), I could try something else. Any ideas?
