Dancing Spaghetti – A Lesson in Density

Who knew noodles could dance? Head to the kitchen, grab a handful of pasta noodles along with a few other materials and get ready for a science pasta party. This is some kitchen science that will have you learning about volume and density in a brand new, hands-on way!


  • Clear drinking glasses
  • Pasta noodles (cooked or uncooked)
  • Water
  • Vinegar
  • Baking soda
  • Food coloring
  1. Measure 2 cups of water and pour the water into a clear drinking glass.
  2. Measure 2 cups of vinegar and add it into the clear drinking glass with the water.
  3. Add 3-6 drops of food coloring to the water and vinegar mixture.
  4. Add some pasta noodles to the glass. How much pasta? It’s up to you! (We used uncooked noodles)
  5. Drop 1 tablespoon of baking soda into the glass. Be ready… adding the baking soda into the mixture might get a little messy!
  6. Watch closely and check out all of those dancing noodles!
  7. Are your noodles done dancing? Add more baking soda to the glass and start the dance party all over again.
What will happen if you use other kitchen foods like raisins, candy hearts, beans or Cheerios? What else will work? Leave us a comment below with your favorite dancing food.
