Toilet Paper Experiment

INVESTIGATION FOLLOWUP

Procedure

My science experiment was to test toilet paper, to find a good toilet paper brand to use. The goal was to find the toilet paper that broke apart the fastest in moving water, the toilet paper that held the most pennies when wet, and the toilet paper that held the most pennies when dry. For the deconstruction test, what toilet paper would break apart the fastest in moving water, I tested the toilet paper by placing a mixer in water and dropping a 2 by 2 inch piece of toilet paper in the spinning water. I repeated this twenty times for each brand of toilet paper. I hypothesized that Scott would break apart the fastest because it was the thinnest toilet paper and one-ply. For the wet test, how many pennies toilet paper could hold when wet, I put a piece of toilet paper on a plastic cup and

Then I dropped 5 drops of water onto the toilet paper and then added pennies until the paper broke. I repeated this 10 times for each brand. My hypothesis for this test was that Quilted Northern would hold the most pennies because it was one of the thickest toilet papers. For the dry test, what toilet paper would hold the most pennies when dry, I repeated what I did for the wet testing but did not put water onto the toilet paper. Instead, I placed a laundry cup taped to a Jenga block in the middle of the piece of toilet paper. I then proceeded to placed 100 pennies in the cup waited 20 seconds, placed a paper towel in the cup then added pennies until the toilet paper broke. I did this ten times for each brand. I hypothesized for the dry test that Member’s Mark would hold the most pennies because it was
