We just did the spaghetti and marshmallow tower. It is supposed to hold an egg in a “earthquake” for 10 seconds. We had a few things that didn’t go well. Unfortunately, we couldn’t make it all in one day, so the marshmallows harden and it was very hard to get the rest of the tower made. As you can see are base isn’t very well built so the tower started to lean. Some things did go well. The cube at the top is good, and the egg sits right on top of it. Overall, I tower was fine, but it had a lot of downs to it.
