Sturmtief Herwart hatte es in sich. Grund genug nach fast 10 Jahren mal wieder auf`s Brett zu steigen. Von "geil wie immer" bis "oh, bin etwas aus der Übung" war alles dabei.

Vacilando a un colega en la ETSAM. El boomerang creo recordar que rodea la barra de la lámpara y a mi colega, pero no me acuerdo y en el video no se aprecia. Es un boomerang preciso y de muy muy corto alcance (aun menor que el famoso Roomarang) ideal para volar dentro de una casa, con viento cero (aunque soporta una suavisima brisa) La única pega es transportarlo porque si se dobla se fastidia pero estoy tratando de hacer uno que quepa en una carcasa de CD. DETALLES: Boomerang en hoja de polipropileno como la cubierta de plástico rugoso negra o blanca de algunos cuadernos. ¡No es acetato! El acetato se usa en la mayoría de tapas de encuadernaciones pero es más liso, se vuelve blanco al doblarlo, y es quebradizo si se golpea de canto (algún boomerang se me rompió así, siempre con acetato). El polipropileno de encuadernar es más fino y flexible que el acetato, y no lo conozco transparente. Este diseño está sacado de www.kbn3.com/bip/index2.html pero sustituyendo el cartón por el polipropileno e imprimiendo en A4 en vez de en A3. Alcance -2m. Radio del boomerang: 10cm, lo que hace una envergadura de unos 17cm. Boomerang made on a SHEET of polipropylene like those found on some notebooks or photocopied documents. It's not acetate! Acetate is not as flexible and thin, and is more fragile if hit on the edge. Boomerangs made on acetate broke with a glass-like fracture when hit this way. This design taken from www.kbn3.com/bip/index2.html but made on polipro and printing on A4 (210x297mm) instead of A3. Size: radius: 10cm, wingspan: ~17cm

The yellow stingray (Urobatis jamaicensis) is a species of stingray in the family Urotrygonidae, found in the tropical western Atlantic Ocean from North Carolina to Trinidad. This bottom-dwelling species inhabits sandy, muddy, or seagrass bottoms in shallow inshore waters, commonly near coral reefs. Reaching no more than 36 cm (14 in) across, the yellow stingray has a round pectoral fin disc and a short tail with a well-developed caudal fin. It has a highly variable but distinctive dorsal color pattern consisting of either light-on-dark or dark-on-light reticulations forming spots and blotches, and can rapidly change the tonality of this coloration to improve its camouflage. Relatively sedentary during the day, the yellow stingray feeds on small invertebrates and bony fishes. When hunting it may undulate its disc to uncover buried prey, or lift the front of its disc to form a "cave" attractive to shelter-seeking organisms. This species is aplacental viviparous, meaning that the developing embryos are sustained initially by yolk and later by histotroph ("uterine milk"). Females bear two litters of up to seven young per year in seagrass, following a gestation period of 5–6 months. Though innocuous towards humans, the yellow stingray can inflict a painful injury with its venomous tail spine. This species is taken as bycatch by commercial fisheries and collected for the aquarium trade; it may also be negatively affected by habitat degradation. Nevertheless, it remains common and widespread, which has led the International Union for Conservation of Nature (IUCN) to list it under Least Concern.
