Stanford University ’s Manu Prakash , PhD , loves coming up with cheap , rugged scientific equipment , likehis 50 - cent microscope made of folded cardboard . Now he ’s followed that up with another ingenious chemistry tool : A$ 5 equipment that uses the guts from a euphony boxto ascendancy chemical substance reaction with top-notch precision .
Dr. Prakash ’s hand - crank up chemistry set use a newspaper punch card to control the flowing of up to 15 unlike chemical substance . Each hole punched in the card triggers a mechanism that delivers a individual driblet of chemical into the chemical reaction chamber . Punch cards can be pluck to moderate the amount and timing of each chemical increase , make eminent - preciseness experiments as simple as turning a lilliputian crank .
“ In one part of our lab we ’ve been focusing on frugal scientific discipline and democratizing scientific tools to get them out to masses around the reality who will habituate them,”Dr . Prakash told Stanford Report ’s Amy Adams . “ I ’d started think about this connexion between science Department of Education and global health . The things that you make for kids to research science are also precisely the form of thing that you need in the field because they need to be full-bodied and they need to be extremely versatile . ”
Just like Dr. Prakash’sfolding microscope , the paw - cranked alchemy exercise set is envisioned as a elbow room to bring accurate alchemy to the field . The team envisions use including H2O testing , medical diagnosing , and key malice type in snakebite victim . Since the accurate metering of private chemical is handled by the equipment , and the user never needs to touch the chemical substance , even an inexperienced substance abuser could function an precise chemical substance tryout .
The music corner chemistry set might not make much healthy , but its promising capabilities are music to our capitulum . [ Stanford ]
