Why Do These Liquids Look Alive?
Why do droplets of food coloring attract, repel, and chase each other? Snatoms molecular models: http://igg.me/at/snatoms More about this topic: http://wke.lt/w/s/VRjRQ Original paper on droplets:...

Watch what happens when I place some small drops of food coloring on to this slide.Some are attracted to each other and merge,while others repel and chase each other.It looks just like the tiny world of micro-organisms, but why?Well if you want to try this out for yourselfYou need to get some ordinary food coloring and dilute it with distilled water using a pipette.Then pass the microscope slide through a flame for about thirty seconds.Let it cool, and then put some drops of different concentration on to the slide.You'll find that drops of similar concentration attract each other and mergewhile drops of different concentrations chase each other.You can draw guides on the slide using permanent marker, which is hydrophobicand set up long distance pursuits.O...
