This is my paper boats I love doing stuff like this. I did make them both out of different types of paper the green one was made out of card and the red one is just normal printer paper. I thought because the paper is dyed it would die the water but it didn't and I was kinda shocked. I ended up timing them as well the red one lasted 11 minutes and the green on 15 minutes. I think the green one lasted longer because it is thicker paper and could handle the water where the red one was thinner and just soaked it right up. Over all I thought it was a fun activity to do I just found it hard to make the boats.
