We found that if we started with a base as circle it was easier to stack the marshmallows. We found it was very hard to stack one marshmallow on top of the other.

When I made my marshmallow Tower it took me two try untill it didn't fall over. I tried a triangel base the first time, but it was too tall and didn't have very much surpport in the middle. The second time I also did the triangel base but used more supports and made it not as tall, and it worked!

When I made a marshmellow tower I made it about 5 feet high and it lasted for 4 whole weeks and then it started to get gooey and melt. So I threw it out.

Christa, age 12 of Mobile, AL wrote:
First off, I tried many shapes for the base. All of them worked for me. The trick is the top structure. At the top I ended up with a pointed top so I made an x coming out of the marshmallows and made a square around it. You might have to double, tripple, or quadrouple the sticks depending on the size of the object on the tower. I also tried a model lower to the ground and that worked the best.
