Frugal Science and Musical Comedy July 18, 2017July 17, 2017 Need a break from the negative? Watch this TED Talk: Inventor Manu Prakash turns everyday materials into powerful scientific devices, from paper microscopes to a clever new mosquito tracker. From the TED Fellows stage, he demos Paperfuge, a hand-powered centrifuge inspired by a spinning toy that costs 20 cents to make and can do the work of a $1,000 machine, no electricity required. Or watch Mozart with a sense of humor. (Thanks, Mel!)
