The needle sink in water because we put the needle in water...
I think it's because the ice has a lower density than water, while a needle has a higher density than water, when it's metal anyway. If a needle is made of bone, it'll float.
Mass is irrelevant; the density of the needle is greater than the fluid it's in (water), while ice is less dense than water.
The ice is the water and if you mean ice like the top part only like thick then its because its really light and a nail is small and does not take up much space
Whether an object sinks or floats depends on its density.
You divide the grams by the density.
Found this on a Internet blog dated in 2011: $100 a gram $350 an eight ball $650 quarter oz $1150 half oz so 22 grams would be about $1600 $2000 oz. an oz. This person recommended the use of a bullet (.05g per snort) which remeasures the amount of meth ensuring that one does not do too much. Use of a bullet last much longer than measuring the amount by eyeballing it which can average anywhere between .1g to .4g per nostril. It is not recommended to use meth by smoking or shooting it. If cut, shooting it allows the unknown cutting material to enter into the blood stream without the normal body filtering system. Smoking it damages the lungs and might be cancer inducing. Plus it stays in your system for a longer period of time than snorting it. However I would recommend not to do meth. It causes paranoia and brain damage in some people and causes others to start using it on a daily basis. If a daily user wants to stop using meth they will find out it is a very difficult task to complete. Also, if one is caught by the police with 5g or more, that person is sentenced to 5 years of jail time, mandatory sentence. Given the benefits vs the consequences of meth use, it is better to stay away from using this drug. $2000 is a lot of money, I rather buy a 55" 3D HDTV than 22g of meth which will only last up to a month before it is gone with nothing to show for it.
