Ceclia, Jackie and I made a thrust structure.
We wanted it to be very strong, so we made a frame out of popsicle sticks, then we bordered it with triangles that we m ade with popsicle sticks. (since triangles are the strongest shapes). We tested our thrust structure out with out bottle three times, and it survived! The bottle didnt always go so high, but our thrust struture survived,
