Oppan Atom Style!

(I made this forever ago, just rediscovered it)

Aerogel, also know as frozen smoke, is the world’s lowest density solid, clocking in at 96% air. If you hold a small piece in your hand, it’s practically impossible to either see or feel, but if you poke it, it’s like styrofoam. It supports up to 4,000 times its own weight and can withstand a direct blast from two pounds of dynamite. It’s also the best insulator in existence.

Chemistry at its finest

can i eat that

Why don’t we use this for everything?!?

This shit is about the coolest thing ever. 


It’s such a great insulator that a thin layer of it will protect anything from the heat of a bunsen burner.


Even though it’s incredibly light and has an extremely low density, its lattice-like molecular structure makes it able to hold objects much greater in mass.

What if you got loads of it, and made a bed, you could pretend you were a pegasus

Possibly one of the coolest things I’ve ever seen.

Again, because science boner.

so oxygen went on a date with potassium today…it went ok.

i thought oxygen was dating magnesium…omg

actually oxygen first asked nitrogen out, but nitrogen was all like “NO”

I thought oxygen had that double bond with the hydrogen twins

looks like someone’s a HO


i’m done with all of you

Acoustic Levitation

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.
