[video] 'Voyager 1 at the final frontier'
As Voyager 1 approaches its 35th birthday, it also approaches the edge of the heliosphere - the range of the sun's magnetic field.
As it does so, the number of rays hitting it, as part of the ISM (inter-stellar medium) are sharply increasing (as shown on the graph).
This is because, like Earth's magnetosphere protects us from solar radiation, the Sun's heliosphere protects the Solar System from cosmic radiation.
It's just so exciting! Nothing man-made has ever been as far from Earth as the Voyager crafts, which are currently 18,000,000,000 and 14,700,000,000 kilometres away from home, respectively!

[video] How does stone skipping work? With a little help from a high-speed camera, you can see the dynamics in action!

[video] 'Fountains of droplets in oscillatory meniscus'
A fascinating video of air in an upturned glass, interacting with the water's surface, when the glass is vibrated.
Hint: really cool looking waves!

Plus some awesome slow-motino shots of things splashing into other things

[video] 'Drops of liquid oxygen levitating and dancing in a magnetic trap'
Oh, this is fantastic! Oxygen becomes paramagnetic at low temperatures, and floats on its own layer of vapour, so can be manipulated using magnets.
Just look at the droplets go!

[video] Accelerated footage (from 1996 to 2004), taken by the Hubble telescope, of supernova 1987A.
The shock wave emitted during the core's collapse can clearly be seen, as it illuminates the outer husk of the star.
