Our tower was 39 cm tall. We had a cradle for the egg. It is like a nest and we hope it does not tilt to much. We have two support beams on the side of the tower so that it does not tilt to much. We have supports going across the tower on the inside so it does not fall over or collapse on the inside.

Boat For Science
We had a piece of styrofoame as the bottom of the boat. Then we had a half of a styrofoam cup hot glued on, on top of that we had another styrofoam cup hot glued on. On the front we had two half straws glued on. We will have two stacks of three popsicle sticks on each side of the two cups, and on top we will put a paper on so it will be a sail. I hope we make it under 10 seconds and maybe be in the top three.
