Chemistry Set For All Ages Takes Inspiration From The Retro Music Box
Device that requires zero experience, and can test water supplies for just $5.
Manu Prakash, an assistant professor in bioengineering at Stanford University, recently came up with a hand-cranked chemistry set that works just like a music box to create precise chemical reactions. At just $5, it’s not simply a toy for kids, but an accessible way for anyone to create their own experiments.
The devices uses a paper punch card, which can be configured to deliver different amounts of chemicals at different times, to control exactly what chemical reaction will take place. It can be configured with up to 15 different chemicals, and once set, requires nothing more than the turn of a simple hand crank.
