B) The ping-pong ball always moves to the centre of the bowl.

C) The table tennis ball dips deeper into the water than at the beginning of the experiment.

D) The table tennis ball dips less deeply into the water than at the beginning of the experiment.

Advice of the day:

Please make sure that the glass is "overfull", i.e. the water is higher than the edge of the glass. The glass should also not be too large. A drinking glass, e.g. a mustard glass works best.
