1. Begin watching the video below, and pause at 1:20. Estimate the length of the pipe, and make a quick calculation of the time it should take an object in free fall to pass through. Now compare this to how long it took the magnet to fall through.

2. Make a guess as to the reason it takes so long for the magnet to fall through the pipe, and explain in detail the Physics behind it.
