In what?
Find out the density (mass/volume) of a marble per gram and compare it to water (1.0)
If it weighs more than 1.0g then it sinks.
Sink
Yes, a cork will often float on the surface of water, depending on the cork's density. But a marble will sink in water because of its weight. It will not float on the surface.
Glass.
This is ROCK so it will SINK
denser things sink faster the denser it is then the faster it will sink
Sink
there is a safe behind the picture in the bedroom the code for it is under the sink 2nd drawer from the left
Because they are denser than whatever you have put them into — water or thin mud for example. Gravity pulls them downwards.
Because the marble has a lesser density than water. And also because of the marbles shape and size. :)
You weigh it in some water and if it float its density is less than one and if it sink its over than one
He will have 13 blue marbles and 10 green marbles.
For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
10 Green marbles, 13 Blue marbles.

He has 10 green marbles.
There could be 12 white marbles and 16 red marbles
