Is terminal velocity a factor in achieving a spherical shape? Is that part of the reason for the height of the tower, or is it just cooling time?

- jd007 13y agoI think a falling ball of lead would have a very high terminal velocity, as it is quite dense and in a rounded shape. I doubt it has much of an effect at the height needed to make these shots.
- sswaner 13y agoAbout 90 m/s, depending on elevation.
- ColinDabritz 13y agoIt sounds like cooling time, from the article: "Shot towers were replaced by the "wind tower" method by the end of the 19th century, which used a blast of cold air to dramatically shorten the drop necessary." Neat!
