Here's a video from Chemical & Engineering News about a collaboration between MIT and José Andrés' ThinkFoodGroup to build a better cocktail garnish. Two, actually, but both of them work with surface tension to function. The first is a pipette that works like a water lily: gelatin petals open when they contact the surface of the liquid and close when they are pulled out of it. Meanwhile, a boat garnish (also made from gelatin and printed on on a 3D printer) zips around the surface of the cocktail propelled by a high proof alcohol like Bacardi 151. In the future, all garnishes will move, it seems. Check it out below:
