Warped Perception built a custom transparent acrylic head for a four-stroke engine so we can see what internal combustion looks like as it happens. He fed the engine with different types of fuel then captured the results in slow-motion. Amazing stuff.
Awesome Slow Motion
Fans of Mythbusters will immediately recall the havoc they wreaked whenever they placed objects at the end of New Mexico Tech’s rocket sled track. The Backyard Scientist decided to build his own miniature version and loaded it up with a knife, slicing various things in twain.
SmarterEveryDay looks at the behavior of the unusually strong Prince Rupert’s drop when subjected to the firepower of a bullet. The 150,000 fps slow-mo footage reveals some truly fascinating properties as shockwaves travel through these tadpole-shaped glass droplets.
The Slow Mo Guys filmed themselves waxing off patches of their leg hair at 28,000 fps. Our hairs really don’t want to come off that way. Props to Gavin for the realistic sound effects. We didn’t ask for this, but now we want to them to redo it with a macro lens.
This unique display piece makes objects placed inside of it appear to move in slow motion. The trick is the use of an electromagnet and strobe lights that blink so fast you can’t see them. It only makes sense that it was designed by Time Warp host Jeff Lieberman.
The Slo Mo Guys turn their attention to a kind of destruction that isn’t permanent, this time building a jumbo jet out of LEGO then smashing it in front of their high-speed camera. The devastation was impressive, but the only real consequence was picking up all those bricks.
While much welding is done by adding molten hot metals with a torch or electrical current, friction welding creates strong joints by rubbing metal together at a high speed. Here, two blocks of titanium are merged into one. If you thought that was cool, check this out.
