Earlier this month we shared a clever 9-layer density column demonstration you’d most certainly not want to drink. This smaller demonstration, however, is a delicious column of fruit flavors.
The secret sauce? In the previous experiment we shared the secret was using fluids with naturally varying densities (such as lamp oil and vegetable oil); in this experiment you’ll be relying on varying amounts of sugar in each layer to change the density of the water and keep them separate (and edible). You’ll need some Skittles, a few drinking glasses, water, and for best effect, a tall and narrow glass or graduated cylinder.
Hit up the link below for the full details on the experiment and tips on how to carefully layer the liquids.
