Harry Potter and Science

It seems that some of the amazing things used by fictitious famous wizard, Harry Potter, are becoming a reality. Last year, an invisibility cloak along the idea of the one Harry wore to go unnoticed through the halls of Hogwarts, has been tested in a lab. Now, add floating water! Researchers at Argonne National Laboratory, Chicago, Illinois, have gotten water droplets to float in the air. Instead
of using magic wands, they using sound waves. Drops of water have been suspended in mid air using a device called an acoustic levitator( developed by NASA). Two tiny speakers, one above the other, send out sound waves just above the range of the human ear.When the sound waves are aligned at just the right point,the two sound waves interfere with one another,eliminating the effects of gravity on the small water drops. The result, the water droplets float in mid air.

You might wonder just what scientists could be able to do with suspending droplets of water or other light object. Researchers hope the process will help them make better pharmaceutical medicines. Creating medicines without the need for a container would slow the evaporation process,making drugs that would absorb into the body more effectively.
