Lighting can be rather fascinating and if you ever witness something got struck by lighting in real life you know that nature can also be really badass. And how awesome would it be if you could capture lightning not just on photo but also within a sculpture?
Lichtenberg Figures can capture a lighting bolt in a glass box forever.
Lichtenberg Figures can be created within solid insulating materials, such as acrylic or glass by injecting them with a beam of high speed electrons from a linear electron beam accelerator. Inside the accelerator, electrons are focused and accelerated to form a beam of high speed particles. Electrons emerging from the accelerator have energies up to 10MeV and are moving an appreciable fraction (95 – 99+ percent) of the speed of light (relativistic velocities).
If the electron beam is aimed towards an acrylic specimen, the electrons easily penetrate the surface of the acrylic, rapidly slowing down as they collide with molecules inside the plastic.
And as you can see it’s like you’re trapping a lightning bolt in a glass box forever. The awesome result is that you now have a force of nature on display.
Nowadays, it’s a universally accepted theory that the universe began 13.8 billion years ago with the Big Bang. But did you know that two radio astronomers unintentionally stumbled upon its discovery?
In the 1960s, Robert Wilson and Arno Penzias were measuring the brightness of the sky with their radio telescope. No matter where they pointed it, they picked up an inexplicable droning sound. What initially sounded like a mistake ended up being the discovery of a lifetime.
This unreal experiment allows you to see air movement around any object.
This is a demonstration of the Schlieren effect. This setup allows you to see changes in air density. The point light source is aimed at the concave mirror. The concave mirror reflects to a focal point. There you use a sharp edged object to partially block the light which helps create a shadow effect that allows you to see air movement.
