I combined everyday soap bubbles with exotic ferrofluid liquid to create an eerie tale, using macro lenses and time lapse techniques. Black ferrofluid and dye race through bubble structures, drawn through by the invisible forces of capillary action and magnetism.

Get Short(y)
How Long Should You Make that Youtube Video?
Data to support the hypothesis that shorter videos get more views. From my own sampling, I’d say a lot of youtubers don’t know how to edit video; all too often the “good part” is well into the video, and the boring set-up is often much longer than it needs to be.
Full of Sound but not Much Fury
Yay, more Vi Hart!
Because Firing Guns Underwater is Important, That's Why
I performed an experiment to see what the differences were between semi-automatic pistols and revolvers. The advantage of shooting under water is that you can see the boundary of the gas flow fields almost perfectly.
I Didn't Know Rainbows Were So Controversial
They’re so very polarizing…
Polarized rainbow, what does this mean???
Rainbows are created when sunlight reflects inside water droplets, bouncing back to you. When the light enters the droplet and also when it leaves, it bends a little bit as well (like how a spoon looks bent in a glass of water). Different colors bend by different amounts, so the sunlight colors get spread out, forming an arc in the sky.
The light forming the rainbow gets polarized when it reflects off the back of the raindrop. The amount of polarization is pretty strong, as the video shows. When I hold the glasses horizontally the light gets through, but as soon as I rotate the glasses, the rainbow disappears entirely! Almost all the polarized light is blocked, and the rainbow vanishes.
But wait, there’s more!
This is the same effect that makes it easier to see through heavy rain or fog with polarized sunglasses.
A Dog Named Van de Graf
Oh Buoyancy!
A man who obviously has a “girth” larger than the inner radius of a floating inner tube, appears to have gone through it unscathed, both for him and the inner tube.
The inner diameter of the tube is around a meter (I’m guessing this guy is bigger than a 40-in waist). If the tube part is 10 cm across, that’s about 8L of volume being submerged, displacing 8L of water, exerting ~80N of buoyancy force, or more than 17 pounds. Another way to look at it is if you filled the tube with water it would weigh that much. Is it reasonable that the man’s “spare tire” would hold that up? In addition to the malleability of flab, water is a pretty decent lubricant.
Not Affiliated with Möbius Strip
Twenty-one large triangles animated by Melbourne, throughout Federation Square. MÖBIUS is a sculpture that can be configured into many cyclical patterns and behave as though it is eating itself, whilst sinking into the ground. The result is an optical illusion and a time-lapse of people interacting with the sculpture and moving through Melbourne’s landmark location throughout the day.
Rhett Knows if You're Faking It
The trick was to use a tripod for the camera and then add fake camera motion. If you use a tripod, it is easier to add fake stuff to your video. However, if you use a tripod people are more likely to think the whole thing is set up.
The un-tripoding trick is what they did with this fake baseball video. How do I know? I will show you.
A Water Bridge in Air
[T]he floating water bridge remains stable without breaking for big aspect ratios and unbent by gravity due to the effect of the induced polarization forces at the interface, generating normal stresses that counteract not only capillary forces but also gravity.
