If you cut a bit of it there is a flat surface and then ridges of cardboard of top. The little ridges have air trapped in them, which causes the cardboard to float.
You really can't:)) Cardboard gets soggy in water and will eventually sink, no matter what. however, do you have clay? You can make it into the shape of a boat, let it dry, and I think it will float. However it probably would sink if you put it in a kiln so don't do that. Also tell whoever you plan to five it to that you should only put it in water a few times. If you really want to make it out of cardboard, only put it in water once, after that if you put it in again it will be so soggy it will get all mushy and sink and start to fall apart. Make sure that the boat does not have holes.
It will float until the cardboard becomes saturated and eventually sinks.
Usually - yes. Objects made of cardboard can float - at least until they become saturated with water. Even a sheet of cardboard will float initially. If the cardboard is coated with something that prevents the cardboard underneath from soaking up water, the object can continue to float for quite a while. Once it becomes saturated with water, cardboard will have more difficulty floating. Since it is made from paper - which derives from wood pulp - even when wet, it will tend to float rather than sink because wood is usually a bit less dense than water. Since it may not be JUST paper, it may depend on what else was added as to whether it will still float when soggy. It all depends on the average density. Note that as it becomes soggy, cardboard may tend to disintegrate - at which point it would just be a mass of mush rather than recognizable as cardboard.
You just need so good cardboard, some strong felt wrap and your imagination!
There are many excellent sites on the internet with step by step instructions on how to build things out of cardboard. The problem with your question is that you don't state whether you want a full size boat that will float on water, or a cardboard ship play house, or a table size model ship. Without that information, the best advice I can give you is to type How to build a cardboard ship into your search box, and choose the site that will be the most help.
A cardboard baler is designed to compress cardboard just as a haybaler does to hay. It can be used for cardboard that is being recycled or for cardboard that needs to be transported.
You would call strong cardboard 'cardboard'. It doesn't matter how strong it is, the cardboard is still cardboard. Even if the cardboard is extremely stiff, it is still cardboard, and there is no special name for it.
I will suggest coating the bottom of the boat with tape and make sure u tape the angls and make sure there are no holes in the boat. also coat the inside and add another layer of cardboard to the boat preferbly slightly smaller then the bottom of the boat. SIGNED DORIAN CLARK. hope this helps
