The fist tower did not go well at all. It was really wobbly and fell over. Then it hardened like that and we tried to fix it but the base just kept breaking more. In the test we set the egg in and then it just rolled out. We managed our money well and so we had enough to buy a new egg. We ripped the bottom part off the tower so it was just the top triangle was out tower. That was really sturdy, but it was only 19cm. That was better than 0. We tested that one and it stood up the whole time. My favorite part was seeing it stand up the 2nd time. My least favorite part was when we tested it the first time and it fell out right away.
