Speedy Train Technology Finds New Food Safety Niche

A team of chemists at Harvard University in Cambridge, Mass. has developed a palm-sized maglev apparatus that can be used to determine densities of various substances, quickly and accurately.

To create a mini-maglev device, Mirica and colleagues suspended a fluid-filled vial between two ice cube-sized magnets.

They found that samples of milk, peanut butter and vegetable oil placed inside the vial would levitate a certain distance between the magnets. The distance, measured by a ruler, directly correlated with the sample's density.
