Water Flow Experiment

Is it possible for water to flow in a line that isn't straight? Can it curve along a line? Can it beat gravity? Let's find out!

  1. Ages: 5 - 8

  2. <30 minutes

  3. A little messy

Step-by-step tutorial

  • Step 1

    We knew that water flows in a straight line--but is it possible for it to flow differently? Are other water molecules a strong enough force to pull it in a different direction?

  • Step 2

    First, we soaked our string in water for a minute or two; the water molecules will long to stay together, and that's what is going to make our gravity-defying stream work!

  • Step 3

    We tied the string onto our weight (a rock).

  • Step 4

    We tied the other end of our string to the handle of our measuring cup.

  • Step 5

    Maddie put the rock at the far end of our pan--stretching our string out as far as it would go, and slowly started pouring.

  • Step 6

    Excellent! "This is so cool how the water follows the string!" How wide can we make our stream of water?

  • Step 7

    How steep can we make the angle?

  • Done!

    Will a heavier string hold and attract even more water? Maybe you'd like to find out!
