Homework Equations

e.g. why some potatoes float and other do not

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?

Addendum:

I am supposed to do some tests to collect detailed information as well.
