Unfortunately, I'm at home now and we don't meet till Friday so I can't be terribly specific. Today we changed it so it's 2 11 inch pistons with 1.5 inch diameters, but that's all I remember, we actually hit the ceiling with that setup. The one in the video is pretty beefy, if I were to make a rough estimation, it's around 15-20 inches long with a 3 inch diameter, I don't know beyond that, we did this fairly haphazardly without any calculations or anything and just stumbled upon something that worked.
