My son took some scraps out of the recycle bin and gathered the materials he needed to make this:

Mama, want to ask me what my inspiration was?

I made a boat out of cardboard, duct tape and two bottles. I made a boat called Motorboat Lightening. It was not that easy. It was kind of hard because I had to do all that in one day. I was going to use foam but I knew I couldn’t find any so I used a water bottle I drank in the car. It was an experiment. What things float and what things not. I got a big pool and filled it with water. Only 2 things sank and a whole bunch of other things floated. A toucan mask sank and so did a rat mask. All of the other things I put in there floated. My boat floated because it had 2 bottles underneath. I put tape so water wouldn’t come in the bottles. I three doubled it. I’m going to make something else, I don’t know what it’s going to be yet.

Edit from the Boy: “Never ever put a cardboard structure in the tub because it will dissolve.”
