HMMMMMMMM. But I can easily throw higher than the mjc hall roof. And outside = wind so that takes more string due to distance travelled forward/back/sideward.

Why can't you start the timer when you launch it?

Yea, the easiest way would be to time it from when you launch it to when you catch it. Then just do what Sean said to calculate the height. I have done this in physics except we were shooting tennis balls out of a combustion cannon.

The formula is:
s = ut + 1/2 at^2
Where
s = vertical displacement
u = initial velocity (0 as it is measured from its peak)
t = time from launch to catch
a = gravitational acceleration (9.8m/s/s)

So yea, to summarize: Do what Sean said, the string wouldn't work. Well it might work, but it would be easier to just time it and use the formula.
Say Whaaaat?

Yes - that's exactly the point.

A stopwatch would be the most accurate - using physics to calc the height.

The hardest part would be the accuracy on when the diab is let go and caught
