3.  Does the surface affect how long a suction cup sticks to the surface?

4.  I predict the suction cup will stick best to stainless steel.

5.  Suction cup  A Wall. Stainless Steel Trash Can  Radiator (Metal)  Watch

6. Procedures  Get materials  Firmly Stick suction cup to surface  Start timer  When suction cup falls off, stop watch.  Record the amount of time the suction cup sucked.

7.  I concluded that suction cups stick well to trash cans but not plaster walls. If I did this again, I would stick to glass and other stuff which I wanted to do but I was too lazy and I only used stuff where the suction cup didn’t suck for very long.
