Tape Adhesion Strength on Steel
Medium
Which type of tape holds the strongest grip on a smooth surface? Adhesive tapes are made with different backing materials and glues. These differences change how much force it takes to pull them free.
You stick five types of tape to a steel plate: cellophane, duct, scotch, electrical, and masking tape. A string hangs from each strip. You add weights to the string until the tape gives way. The total weight at failure measures the adhesive strength.
Duct tape holds the most weight before letting go. Electrical tape fails under the least force. The range between the weakest and strongest tape is surprisingly wide.
Hypothesis
The hypothesis is that the duct tape will require the greatest amount of force to be pulled off the steel surface.
Method & Materials
You will place two stools about 400mm apart and place a metal steel plate on top. You will then cut pieces of tape and stick them to the steel plate. You will then hang weights from the tape and measure how much weight it takes to pull the tape off the steel plate.
You will need a roll of cellophane tape, duct tape, scotch tape, electrical tape, and masking tape. You will also need two chairs or stools, a metal steel plate, five pieces of string, and weights.

The results showed that the duct tape was the strongest among the five types of tape tested. It required the most force to pull it off the steel surface.
Why do this project?
This science project is interesting because it tests the strength of different types of adhesive tape. It also shows how different types of tape can be used for different applications.
Also Consider
Variations: Repeat the experiment with various other brands of the same types of tape. Try to repeat the science fair project using double sided tape.
