      Hi @ninjanae
      Thanks for the question – this is a good one.
      Your mass is always the same, wherever you are, but when you are in water, there is pressure from the water molecules on you, and some pressure pushes you upwards, against gravity. This is why you weigh less.

      Hope this helps!
