Because they are denser than whatever you have put them into — water or thin mud for example. Gravity pulls them downwards.
You weigh it in some water and if it float its density is less than one and if it sink its over than one
Uranium marbles contain up to 3 % uranium; these marbles are fluorescent under an UV light.
one of marbles uses are counter tops
because ages ago they used to use marbles instead of glass balls.
There has to be 12 marbles in the group. If 4 are red that is 1/3 of 12 and if 3 are blue that is 1/4 of 12. The rest can be any color. That is how you explain how four red marbles can make up 1/3 of a group of marbles and three blue marbles make up 1/4 of the same group :)
Sink
there is a safe behind the picture in the bedroom the code for it is under the sink 2nd drawer from the left
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.
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.
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.
He has 10 green marbles.
There could be 12 white marbles and 16 red marbles
at least 39 blue marbles
