Nebel in einer Seifenblase und ein schwebender Kreisel

Dustin Skye macht interessante Experimente mit einem schwebenden Kreisel.

Taking it to the next badass level. This is a Levitron. It’s a top that floats due to magnetism and gyroscopic stability. The wooden base contains a large ring shaped magnet that repels the top which is a small ring shaped magnet. The spinning top creates a gyroscopic effect that prevents it from flipping over in the large magnets field. The tray and hoop are items I made. The fog comes from an electronic cigarette (E-cig) that I modified to create fog with pure glycerin. I’ve installed a line to the tray with which I add a small amount of propane to the bubble dome. The top falls shortly after I light the bubble dome on fire because it’s made of neodymium. Neodymium magnets produce weaker magnetic fields as they are warmed up and stronger magnetic fields as they cool down.

Superstarke Magneten zerstören Dinge in Slow Motion

Da sollte man wohl eher nicht die Fingerchen zwischen stecken.

Watch as two super-strong neodymium magnets jump together in slow motion, destroying a variety of every day items. Will it squash, smash or explode? See how an apple, an iPhone, a plastic cup full of rainbow drops and a carton of juice stand up to the awesome power of two 50mm x 50mm x 25mm N42 neodymium magnets.

DO NOT TRY THIS AT HOME. This video was recorded by trained professionals in a controlled environment.

Ein Tisch aus aneinander schwebenden Holzwürfeln

Nicht wirklich praxisnah, dass Dingen. Wenn man der Großtante darauf den guten Bohnenkaffee im Familien-Porzellan serviert und dann beim Setzen mit dem Knie dagegen stößt, gibt es sicher eine Riesensauerei und der gute Orientteppich muss derbe leiden. Aber ein echter Hingucker mit wahrscheinlich ziemlich hohen Spaßfaktor: The Float Table.

The Float Table is a matrix of „magnetized“ wooden cubes that levitate with respect to one another. The repelling cubes are held in equilibrium by a system of tensile steel cables.

It’s classical physics applied to modern design. Each handcrafted table is precisely tuned to seem rigid and stable, yet a touch reveals the secret to Float’s dynamic character.
