Science tower

We made at tower out of spaghetti and marshmallows and tape.  The building of the tower was great and the tower felt sturdy but when we have to put an egg in it and put it in the earthquake simulator the egg stayed in it for 5 seconds of the 10 seconds it was supposed to stay and then fell out. It was unfoutunate since we wanted it to stay in the tower the whole time but it didnt. If I had to change something I would have added more spaghetti sticks and tape on the nest part that held the egg. But we were out of money so I could not add any more.
