Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn’t get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this “containerless processing”.
The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic pressure is enough to cancel the force of gravity.
FUCKING SCIENCE MAN
Pretty awesome demonstration of density/buoyancy concepts :-)
Nine Layer Density Tower
Neil deGrasse Tyson and Bill Nye could have made an awesome buddy comedy film.

So I just realized that Neil deGrasse Tyson is totally the principal from The Magic School Bus…
How else would you explain the funding for a bus like that? SCIENCE!
:D :D :D

Awesome portraits of Bill Nye The Science Guy by Derek Heisler
Bill Nye is my science boyfriend.
I drew this in response to ‘Science: It’s a girl thing!’ which is this ridiculous video.
I work in a lab, as a female scientist.
This be crazy!
Love this lol, can’t wait to see the backlash from the female tumblr community
They shouldn’t “backlash,” unless they don’t understand satire! Which I know a lot of people (sadly) don’t.
My physics major brother and I have this half-joking argument about once a month over whose major is better or does more for society, and he sent me this picture once as a peace offering.
The Deep Space set. Enjoy.
Tomorrow I’ll be working on images of spacecraft and manned exploration of space.
space is awesome and scary.
