The Newspaper Tower

So here is our group's Newspaper Tower. Even though it is not as high as other groups, but i think the top is very unique from others' (The tape is on top like a flag). Further, I think the base of our Tower is steady; it has the shape of tetrahedron, just looks like the camera stand —— the best friend for photographer. Then we just try our best to roll the rest of newspaper as high as possible while as the same time to make it strong (Then use tape to connect all the cylinder shape newpaper together). However, I think we could change one thing so that it could be higher. We used too much newspaper for the base, I think it is a good idea to reduce the usage of newspaper for each foot of the base and put them at the top to make the tower higher. Though we still need to add more newspaper at the bottom to support the top and the whole weight, the height would still be higher. The only excuse that I give is that we don't want to take the risk of the tower falling down. We want to make sure that it could stand at the first place,  and after that, we didn't have enough time.

The Tower with the "flag"

The physics principle that we applied for this tower is: low centre of gravity so that the tower would be stable. Otherwise, the movement of air would make the tower fall. That means the mass at the bottom should be heavier that the top (That's why we used a lot of newspaper at the bottom). Also, I think, for real buildings, we need to use Newton's second Law so that the building would bear the earthquake or other disturbances.
