Here's one I stumbled upon a few days ago.
If you add 100ml of water to 100ml of alcohol, what is the volume of the resulting mixture?
Who stole the difference?
Mmmm, I may be on the wrong tack here but :
If you have an ice cube measuring 4.6416 x 4.6416 x 4.6416, so a volume of 100ml, and you put it into a glass of 100ml of the finest Johnnie Walker the resultant mixture fills a 200ml glass, yet when it melts then the volume would be 190ml. So where has the 10ml gone ?
Well, density of ice is less than water so when the 100ml of ice volume melts it is only 90ml of water volume.
I have tried this many, many times. And each time I got very, very drunk. Also it is only theory because I can't wait for the ice to melt.
