The 5cience

the gallium in the mold has solidified into a spoon! it sounds just like a regular spoon and melts to a liquid puddle in seconds. It's not an acid in which the spoon melts but simply hot water. Several spoon molds and Gallium metal (99,99% pure) available to make gallium spoons like this one!

People have a lot of different ideas about what gravity is: a downward force that stops you from flying off into space, an attraction smaller objects experience towards larger objects, or a mutual attraction between all masses. It is the last of these ideas that best reflects a scientific conception of gravity.

If the Earth were the size of a basketball and the moon a tennis ball, how far apart would they be? Diagrams that are not to scale make us think that they're closer than they really are.

A new technology that allows wireless signals to be sent and received simultaneously on a single channel has been developed by Stanford researchers. Their research could help build faster, more efficient communication networks, at least doubling the speed of existing networks.

I stick my hand (momentarily) directly into liquid nitrogen but don’t suffer any injuries due to the Leidenfrost effect.

The Leidenfrost effect is the formation of a gas barrier between a hot surface and a boiling liquid if the temperature difference is great enough. This gas barrier greatly slows the heat transfer between the two and allows the liquid to last longer and consequently the hot surface to remain hot longer. This effect can be seen in a frying pan as it’s being heated. At first the water quickly boils as it’s dropped in but at a hot enough temperature the Leidenfrost effect takes over and makes the water skate around the surface lasting a very long time.

Liquid nitrogen vs. a room temperature object will also exhibit the effect preventing it from instantly freezing the object… such as my hand.

What really sets us apart from our cousins? Our wonderful memory?

No, not that, either.

This video illustrates that our ape cousins far exceed us in short term memory recall skills. A chimp is shown memorizing numbers with remarkable accuracy at lightning speed.

An amazing bit of footage from the National Geographic documentary “Human Ape”.

A brief, interesting clip from National Geographic’s “Ape Genius” documentary, demonstrating problem solving skills in chimpanzees, by requesting cooperation.

Also shows chimpanzees providing assistance to humans, by noticing assistance is needed, and retrieving out of reach objects for their human companions.

As time goes on, it becomes more and more obvious that the great apes are our evolutionary cousins. I would hope everyone viewing this would be able to share in my astonishment and awe at the brilliance displayed by these amazing creatures.

Strange Gravity Illusion

Check out this poster and how the hallways seem to change perspective when you change the camera angle.

Lance Lund, a professor at Anoka-Ramsey Community College, was asked to prepare a promotional science video for the college back in 1995 that was to air on a local cable access channel. All went well until he inhaled some sulfur hexafluoride (SF6).

This illusion is fairly difficult to see but once you do, it’s amazing. Focus on the rotation of the rod, it appears to continually rotate in 1 direction while the window appears to reverse direction, causing the illusion that the rod passes through the window.

Elevator Floor Illusion

Lilac chaser is a visual illusion, also known as the Pac-Man illusion. It consists of 12 lilac (or pink, rose or magenta), blurred disks arranged in a circle (like the numbers on a clock), around a small black, central cross on a grey background. One of the disks disappears briefly (for about 0.1 second), then the next (about 0.125 second later), and the next, and so on, in a clockwise direction. When one stares at the cross for about 20 seconds or so, one sees three different views:

1. A gap running around the circle of lilac disks
2. A green disk running around the circle of lilac disks in place of the gap
3. The green disk running around on the grey background, with the lilac disks having disappeared in sequence.

This is due to an effect in which the colors of the lilac disks are inverted in the optical illusion to a green color. (If the discs were blue, one would see yellow where the gaps were.)

The amazing everyday wristwatch: We never think about it, but only because engineers have made it so reliable and durable that we don’t
need to. At its heart lies a tiny tuning fork made of the mineral quartz. In this video Bill takes apart a cheap watch and shows extreme

operation.

The Penrose triangle, also known as the Penrose tribar, is an impossible object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. The mathematician Roger Penrose independently devised and popularised it in the 1950s, describing it as “impossibility in its purest form”. It is featured prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

The tribar appears to be a solid object, made of three straight beams of square cross-section which meet pairwise at right angles at the vertices of the triangle they form.

This is one of the easiest tricks to do and the results are truly amazing.

Jem Stansfield visits the Defence Academy of the UK in order to make the dangerous high explosive nitroglycerine. Filmed in extreme slo-mo for the first time ever for ‘Explosions: How we Shook the World’, just a hit with a hammer is enough to cause this sensitive high explosive to detonate – creating a supersonic shockwave and a flash of light that is almost too fast to film, even with the latest specialist cameras.

We present a system for quick and easy manipulation of the body shape and proportions of a human actor in arbitrary video footage. The approach is based on a morphable model of 3D human shape and pose that was learned from laser scans of real people. The algorithm commences by spatio-temporally fitting the pose and shape of this model to the actor in either single-view or multi-view video footage. Once the model has been fitted, semantically meaningful attributes of body shape, such as height, weight or waist girth, can be interactively modified by the user. The changed proportions of the virtual human model are then applied to the actor in all video frames by performing an image-based warping. By this means, we can now conveniently perform spatio-temporal reshaping of human actors in video footage which we show on a variety of video sequences.
