hydrodynamic levitation
Bookmarked 462 weeks ago
on a stream of water you can levitate light balls of all sizes and even disks and cylinders the mechanism is not the bernoulli effectwant to make this at home: my friend blake from innovinci emailed me with a cool idea for a video and footage of levitating balls in water streams initially it was tough to explain the physics of what was going on the standard bernoulli effect relies on the object being completely immersed in the upward-flowing fluid but in this case the water seems to form a single stream around the object and it039s deflected away and down from the stream by newton039s third law the force on the water by the ball is equal and opposite to the force of the water back on the ball pushing it up into the stream there is a stable equilibrium position because if the ball moves into the stream it quotcuts offquot the water going over the ball so it drifts out if it drifts out too far then lots of water passes over the ball pushing it back into the streamspecial thanks to

uplifted - a waterlust short about archimedes039 principle
Bookmarked 530 weeks ago
buoyancy forces are the result of archimedes039 principle which states that an object submersed in a fluid will experience and upward force equal to the weight of the fluid displaced by that object this law of physics is especially important in the field of aqua therapy and allows patients with severe injuries to improve their strength without bearing their full weight music: quotlove is allquot by the tallest man on earthspecial thanks to amazing team at spaulding rehabilitation hospital for their supportlearn more at waterlustorg

computational hydrographic printing siggraph 2015
Bookmarked 574 weeks ago
by yizhong zhang chunji yin changxi zheng and kun zhoutechnical paper at acm siggraph 2015abstract:hydrographic printing is a well-known technique in industry for transferring color inks on a thin film to the surface of a manufactured 3d object it enables high-quality coloring of object surfaces and works with a wide range of materials but suffers from the inability to accurately register color texture to complex surface geometries thus it is hardly usable by ordinary users with customized shapes and textureswe present computational hydrographic printing a new method that inherits the versatility of traditional hydrographic printing while also enabling precise alignment of surface textures to possibly complex 3d surfaces in particular we propose the first computational model for simulating hydrographic printing pro- cess this simulation enables us to compute a color image to feed into our hydrographic system for precise texture registration we then build a physical hydrographic system upon off-the-shelf hardware integrating virtual simulation object calibration and controlled immersion to overcome the difficulty of handling complex surfaces we further extend our method to enable multiple immersions each with a different object orientation so the combined colors of individual immersions form a desired texture on the object surface we validate the accuracy of our computational model through physical experiments and demonstrate the efficacy and robustness of our system using a variety of objects with complex surface textures
