How to Dissolve Toilet Paper for a Kid's Science Project


Toilet paper is used in several ways for kid's science projects. You can use it as the primary focus in experiments to test strength, biodegradability or integration into the water system; the tissue also works as a component of recycling and other "green" science experiments. Dissolving the toilet paper is sometimes a requirement that isn't explained in the experiment's instructions; fortunately, there are a few tricks to remember when preparing dissolved toilet paper for a science project.

Things You'll Need

  • Toilet paper roll
  • Medium-sized transparent jar
  • Stirrer, straw or teaspoon
  • Scissors
  • Soda bottle with lid
  • Place a few sheets of toilet paper into a medium-sized transparent jar. Run water into the jar, filling it three-quarters of the way full. Grab a long stirrer, straw or long teaspoon. Stir the water and tissue mixture vigorously until the toilet paper is dissolved.

  • Fill a soda bottle three-quarters full with water as an alternative way to dissolve the paper. Add a few sheets of toilet paper, cut into strips if needed in order to slip into the bottle. Place the lid on the bottle and shake vigorously, checking occasionally to see if the tissue is dissolved.

  • Add more sheets of toilet paper to the mixture as required by your science project. Repeat the stirring or shaking steps until all the paper is dissolved. Projects involving the use of paper pulp will require the addition of considerably more paper, until the mixture is almost the consistency of a paste.

Tips & Warnings

  • Kapiolani Community College's Lydia Kiefer advises that consumers use about six sheets of toilet paper at each restroom visit. Students performing science experiments on toilet paper strength or effects on septic systems should consider this number.
