How to make an Amazing 9 Layer Density Tower

Water is less dense than honey. Rubbing alcohol is less dense than water. Poured carefully on top of each other, from heaviest to lightest, they can create distinct layers. Add more liquids of different densities, suc...

Surface tension and The Cheerios Effect

Ever notice how cereal clumps up in your bowl, or how cereal sticks to the edges of the bowl? Bubbles in beverages do the same thing. You've probably seen this surface tension and buoyancy at work, but did you know th...
