It was great!!! It actually survived the stability test! They placed the tower in the middle of 2 tables and from inside inserted a rope and tied it at the very top. The other end of the rope was a 10 pound object. then it's suppose to survive the pull of the object for 10 seconds. I was really scared at first. I mean we made an Eiffel tower(actually only the lower half looks like an Eiffel tower. The upper half looks like some bird cage. and the only one holding it were some columns. I didn't even wanna look but when I heard them count till 5 I started to peek. IT SURVIVED!!!
