science experiment on household sealants

Household Water Sealants

My science experiment is about water sealants for paper boats. I got interested in the subject because I recently got interested in origami. As I was looking on the web on origami projects I came across an origami paper boat. Well, I decided to make it and then I was curious to see if it would float or sink. I placed the boat in a bucket of water and it did float and eventually it did sink. I told my friend about the boat and he told me that it would be great to use it in a science experiment. Boats along with other things use water sealants so the water doesn’t sink I learned that sealers contain liquid polymers. Sealers can prevent rust, corrosion resistance, are waterproof, slipping, skidding, and many others. I was curious to see if it would work on paper boats. To make it more interesting I decided to use everyday household items to see if they would work as sealants.


Question: What household item would be the best water sealant for paper boats?...
