DNA is not usually the sort of thing I think of as a delicious way to relax at the end of a long day, but that’s probably because I’m not a synthetic biologist. Oliver Medvedik, on the other hand, is, and in this TED-produced video, the co-founder of New York community biolab GenSpace demonstrates how to extract the deoxyribonucleic acid from a common strawberry by making a pretty decent looking cocktail. All you need are frozen strawberries, pineapple juice, a filter, and some high-proof alcohol. It’s surprisingly simple:

It’s not that I didn’t care about my high school chemistry classes. It’s just that, after spending the first few weeks of the semester trying to wrap my brain around the molar weight of Schrödinger's cat, I realized that no matter how many times I looked at the periodic table of elements, it was never not going to resemble a chess board from hell. Call me “defeatist” – I prefer to think of myself as having embraced the fact that discretion is often better part of valor.

New TED-Ed Platform Aims to Bring TED Talks Into the Classroom

By harnessing the expertise of educators to build out its video library, TED sends the message that teachers matter.


Hundreds of millions of people around the world have learned about more than 1,000 topics thanks to the genius that is TED Talks.
