The boy had to solve the problem of creating a volcano model that erupted realistically, determining the best material for a boat to float the longest, and figuring out how to make a cardboard rocket fly the farthest.
To make clay float in water, you can mix it with a lightweight material such as sawdust or small pieces of foam to decrease its density. By adjusting the proportion of clay and lightweight material, you can create a mixture that is buoyant enough to float in water.
Increase its volume by adding more plasticine. Shape it into a hollow, buoyant structure like a boat or raft. Use a light material, like a small piece of foam, to help it float. Mold the plasticine into a ball shape, which can displace water and float. Create an air pocket within the plasticine to increase its buoyancy.
The shape of a boat with a hull that displaces water creates buoyancy. When the boat sits in water, the displaced water exerts an equal and opposite force on the boat, pushing it upwards. This buoyant force allows the boat to float on the water's surface.
To make plasticine float, you can shape it into a boat or raft-like structure with a concave base. By redistributing the weight and displacing enough water, the plasticine will float instead of sink.
Any material that will float, such as wood or plastic.
Add flotation material to it, like sprayed polyurethane foam.
Yes it does because depending on the materials of the boat and how much their mass is can change the buoyancy of the toy boat. Boat can be designed to have less volume in order for it to have less density and be able to float. So if the material's mass is alot if can make the boat sink. If the material's mass is not alot then it can help the boat float. If the shape is designed to have more volume than mass it will float. If not then it will sink.

Fibre glass is a good material to make boats it is a mixture of glass and plastic.
anything you want that can float. You can be creative.
The key to make a boat float is that the boat should weigh less (or have less mass) than the water it displaces.
