Each student needs:

  • 2 boxes of JELL-O (a powdered gelatin dessert mix), the 8-serving size; pale colors work best
  • 5 bendable plastic drinking straws (cut away the straight parts of the straws from the bendable portions—which will be used)
  • 1 Styrofoam plate
  • scotch tape
  • 1 aluminum plate or pan
  • 1 plastic syringe
  • colored liquid with small particles (such as a small amount of fine sand), for use in the syringe
  • stop watch

Supplies for teacher to make JELL-O Jigglers mix (see instructions in Procedure section):

  • large mixing bowl
  • stirrer
  • boiling water, 2.5 cups per box of JELL-O (using a Mr. Coffee-type machine works well)
  • refrigerator, for cooling gelatin to solid form
