Did you know that water has the power to defy gravity? This science experiment for kids, which doubles as a magic trick, demonstrates how to pour water from a pitcher into a glass two feet away.


  • Cup or pitcher with a handle and pouring spout
  • Water
  • Food coloring
  • About 3 feet (90 cm) of string
  • Drinking glass


  • Fill the pitcher half full of water. Add a few drops of food coloring for a dramatic effect.
  • Wet the string thoroughly. Tie one end to the pitcher handle and stretch it tightly across the spout. Let the other end fall into the glass.
  • With one hand, hold the pitcher by the handle about 1 foot (30 cm) above and 2 feet (60 cm) away from the glass, while the other hand holds the string against the inside of the glass.
  • Say “Abraca-Science” as you slowly pour the water down the string. It sticks to the string, magically making its way into the glass! Experiment to get the slope just right.

The Science:

Although gravity would like to pull the water off the string and onto the ground, there are two other forces that are hard at work in this experiment. Adhesion keeps the water stuck to the string. Cohesion keeps the water stuck to itself. Together these forces keep the water flowing in a stream stuck to the string.

Stick-to-itself force = cohesion

Stick-to-other-things force = adhesion
