Cut out a small rectangle from the cardboard and cover it in duct tape.
Help your child tape the two water bottles side by side to the bottom of the cardboard.
Cut out a triangle and cover that with duct tape as well.
Tape the triangle to the top of the cardboard boat, making a fin or sail.

How do you make a boat experiment?
Directions
Cut a piece of tin foil 5 x 6 inches.
Fold up the sides of the boat so it will not sink and hold a cargo of pennies.
Place the boat in the bowl of water.
See how many pennies your boat can carry before it sinks.
Have some friends over and try this experiment with them.
How do boats float for kids?
Boats float because they are less dense than water. According to the scientist Archimedes, the weight of the water displaced, moved to make room for something else, by an object is equal to the weight of that object.
How do you make a boat float better?
Ways to Add Buoyancy to a Jon Boat
Add flotation pods.
Move some of the heavier items to the front.
Add PVC tubes.
Built-in air cavities for buoyancy.
Adding buoyancy using foam.
How can I make my boat hold more weight?
What type of design makes the strongest boat?
The most stable boat hull design is considered the flat bottom hull. This kind of design offers more stability than the rest due to its flattened bottom. Flat bottom hulls include small boats used in shallow waters, mainly in rivers or lagoons such as small fishing boats.
Wide, flat-bottomed boats will hold the most weight.
Does foam in a boat help it float?
Prevent Sinking
In most cases, flotation foam provides enough time to radio for help and wait for a rescue, or to make it to shore before the boat goes under. In fact, if you have enough foam, it could prevent the boat from sinking entirely, saving your gear and your life.
How much buoyancy is in a 5 gallon bucket?
Each 5 gallon bucket completely submerged would provide about 41 pounds bouyancy.
Why do aluminum boats float?
A giant ship is less dense than water. This is also why your foil boat floats. You folded your foil into a shape that has a high volume which displaces a lot of water. This makes the weight of your boat’s aluminum foil much less than the weight of the water it displaces.
What’s more buoyant air or foam?
Hello Wenceslaus Muenyi, air must be lighter than foam and less dense. But to contain the air you need a super-light container or bubble, a light-weight balloon. this would definitely float higher/better than the equivalent volume of foam.
What material floats best in water?
You can do better than trapped air — helium! It is be so buoyant that even without the water below a balloon filled with it will float away, due to the fact that the buoyant force of the displaced air is greater than the graviational weight of the helium plus the balloon.
Which wood floats the best?
A piece of cedar, which is rather light, will easily float on top of water. Oak, on the other hand, is a much heavier piece that’s often called a hardwood. It still will float, but some of the wood is submerged into the water.
It should give you enough time to reach safety, radio for help and wait for rescue, or make it to shore before the boat goes under. If you have enough foam, that boat literally will not sink. Flotation foam is there to delay and/or prevent a boat from sinking. Think of it as a life jacket for your boat.
Are there unsinkable ships?
The short answer is no. And anyway, it seems the claim that it was unsinkable didn’t come from engineers but rather from advertisements for the Titanic. The ship had a lot of design features—such as the watertight compartments and their bulkheads—that may have led people to believe that it wouldn’t sink.
