Video: For 4/20, here's some mind-blowing physics to get high to

Every year, stoners across the country celebrate 4/20 by gathering in open fields to smoke huge joints, chowing down on edibles, and generally celebrating cannabis culture in all its forms.

Here at Real Future, we prefer to spend our 4/20 tripping out on the nature of space and time. So grind your dankest herb (where legal, of course), fire up your vaporizer, and let us blow your mind with some experimental physics. (Hint: it involves RAINBOW GRAVITY.)
