    <title language="eng">Artificially generated halos: rotating sample crystals around various axes</title>
    <abstract language="eng">Abstract&#13;
&#13;
So far experiments with artificial halos from single transparent crystals have suffered from the lack of apparatus that allows simultaneous rotation around two and three axes. A new setup is presented which overcomes these restrictions by combining electrical as well as pneumatic concepts. This enables reproducible experiments of the most common halos observed in nature and for the first time artificial ring halos from single hexagons rotating around three axes simultaneously. In addition, an old qualitative halo demonstration based on perceived colors of rotating colored areas whose contours represent scattering plots has been reinvestigated and the usually nonsaturated color of artificial parhelia was visualized using a crossed prism method. These new experiments are discussed in the context of all known artificial halo experiments.&#13;

    <title language="eng">The optics and physics of near infrared imaging</title>
    <abstract language="eng">abstract&#13;
A large part of photonics research and development, as well as commercial applications such as optical data transmission or infrared thermal imaging, occurs in the infrared spectral range between 0.8 μm and 15 μm. However, relatively little material is so far available for experimentally teaching the physics and optics of this spectral range. We report a respective new approach in the near infrared (NIR) range between 0.8 μm and 1.7 μm that allows visualization of a number of fascinating physics phenomena. First, we use the near-infrared sensitivity of silicon-based detectors in rather inexpensive video cameras and digital single-lens reflex cameras by removing the infrared-blocking filter and replacing it with a visible-radiation blocking filter. Second, we utilize modern NIR cameras based on InGaAs detectors. With both camera types we illustrate and explain a number of physics concepts that are especially suitable for curricula in optics and photonics. Examples include the strangely bright appearance of vegetation, contrast enhancement between clouds and sky, the initially surprising differences of optical material properties between the VIS and NIR range, the possibilities of visualizing buried hidden structures and texts, and recent medical applications to locate blood vessels below the skin. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    <title language="eng">Bouncing Poppers</title>
    <abstract language="eng">Abstract&#13;
&#13;
Toys are known to attract interest in physics and they are therefore often used in physics teaching of various topics. The present paper deals with a simple toy, the so-called “hopper popper,” which, similar to superballs, can be used when teaching mechanics. We suggest some experiments and describe the basic physics of this toy, also providing background information for teachers.</abstract>

    <title language="eng">The tablecloth pull revisited</title>
    <abstract language="eng">Abstract&#13;
&#13;
A very old and well-known magical trick is the so-called tablecloth pull. A table is covered with a tablecloth, on top of which are certain objects. The task is to remove the tablecloth while the objects—which must not be touched—stay on top of the table. This article describes the physics behind the experiment, and presents examples recorded with high-speed cameras.</abstract>

    <title language="eng">Flickering lamps</title>
    <abstract language="eng">Abstract&#13;
&#13;
Many processes in electromagnetism vary with time. Some of them are well known, in particular those related to line frequencies of 50 Hz or 60 Hz such as fluctuating light output of discharge and incandescent lamps. The flickers of discharge and incandescent lamps have quite different physical principles involved, which are investigated experimentally using high-speed cameras and theoretically using simplified models. The topic is related to other phenomena such as the transient behaviour of phosphor layers covering the screen of oscilloscopes and the time-varying Lorentz force acting on the filament of light bulbs. All studies are well suited for teaching selected aspects of electromagnetism and light at undergraduate level at university.</abstract>

    <abstract language="eng">Abstract &#13;
We present experiments giving new insights into the classical light-emitting pickle experiment. In particular, measurements of the spectra and temperatures, as well as high-speed recordings, reveal that light emission is connected to the polarity of the electrodes and the presence of hydrogen.</abstract>

    <abstract language="deu">Abstract&#13;
&#13;
Das Flimmern der Sterne, von manchen als romantisch empfunden, ist für Astronomen ein Ärgernis. Selbst bei klarer Luft scheinen die Sterne herumzuhüpfen und in ständiger Bewegung zu sein. Das Maß des Seeings, wie die Wissenschaftler sagen, beschränkt das räumliche Auflösungsvermögen von Teleskopen. Mit einer einfachen Versuchsanordnung und einer Hochgeschwindigkeits-Kamera lässt sich dieses Phänomen im Labor nachstellen und analysieren.</abstract>

&#13;
Das Experiment, bei dem eine Essiggurke elektrisch stimuliert leuchtet, gehört zum Standardrepertoire vieler Schulen und Hochschulen. Meist wird es zur Elektrizitätslehre oder zur Atomphysik vorgeführt, inklusive vordergründig einleuchtender Erklärung. Eine genauere Untersuchung zeigt jedoch, dass der Mechanismus komplexer als gedacht ist. Die Lichtemission entsteht in einem Zusammenspiel von Elektrolyse und hohen Elektrodentemperaturen. Dabei regen wahrscheinlich vor allem exotherme Wasserstoff- oder Knallgasreaktionen das Natriumlicht an.</abstract>
