Science

DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!

Double-whammy lighting/heating energy saving tank hack

Double-whammy lighting/heating energy saving tank hack

Flickr user fotogra4er replaced the fluorescent tubes lighting his aquarium with LEDs. Which, of course, make way more light and way less heat for the same amount of energy. Then he upped the ante by cooling the LED lighting bank by circulating tank-water through it, which exploits what waste heat the LEDs do generate to warm the tank-water, and in turn saves power that would otherwise go to the tank heater.

Professor destroys laptop with liquid nitrogen

Physics professor Kieran Mullen of OU apparently has a hard-and-fast rule against laptops in class. To drive the point home, he staged a public execution of one by freezing it in liquid nitrogen and smashing it against the floor, where its broken remains were left as a warning to others. Of course the whole thing is staged and the laptop in question was old and worthless, but hey, any excuse to freeze stuff with LN2 is OK with me.

Superconductor levitates around circular supermagnet track

High-temperature superconductor (Yttrium barium copper oxide) floating in the magnetic field of Neodymium magnets. This phenomenon is called the Meiรƒลธner-Ochsenfeld-Effect and was discovered in 1933. The superconductor has to be cooled with liquid nitrogen which has a temperature of 77 K or รขห†โ€™196 ร‚ยฐC. If it is placed in a strong magnetic field it remains in its position. It also works if you turn the track upside down
