Spongebob’s show would be a lot less exciting if it took place in the real, scientific world. The ocean is a weird place, full of strange creatures and James Cameron.

Your farts may smell like roses to you! But why do other people’s farts smell so much worse?
Also… if farts can spread disease can they spread Ebola?
Enjoy!
It may be crude, but it’s often the case. There’s no other way to say it: most people like the smell of their own farts. But why? As gross and hilarious as it may seem, scientists have confirmed that in a blind smell test, people prefer the smell of their own gas to other people’s brew.

You can actually see sound waves as they travel through the air thanks to a clever photographic trick called Schlieren flow visualization.
Schlieren flow visualization is based on the deflection of light by a refractive index gradient The index gradient is directly related to flow density gradient. The deflected light is compared to undeflected light at a viewing screen. The undisturbed light is partially blocked by a knife edge. The light that is deflected toward or away from the knife edge produces a shadow pattern depending upon whether it was previously blocked or unblocked. This shadow pattern is a light-intensity representation of the expansions (low density regions) and compressions (high density regions) which characterize the flow.
