Structure Testing

We assembled this structure that was supposed to weigh under 22 g but ended up weighing more and it had to hold as much weight as possible in 2 different directions -- you could add weight after 4 seconds. This is the tester that we used to place weight on top of the structure. It held 356 pounds for 20 minutes before it collapsed. Here are some pictures. We are going to test more structures to see what construction method works best.
