Boats that get holes in them.
How do you make a plastic bottle submarine float then sink and float?
put water in to let it sink... then put air into it to let it float...
Do boats sink?
Boats can sink. They are usually made of materials that allow them to displace water, and permit them to float. From time to time, that material will break down, and the boat will sink.
Does a toy car sink or float?
That depends what it's made of ! A metal one will sink, but a wooden or plastic one will float.
What can float and what can sink?
Hmmm. Canned/Tinned fruit will most certainly sink. Most fruits straight off from the tree will float. However, if the fruits are not ripe, they might sink as they are very dense. A coconut will most certainly float. A packet of biscuits (unopened) will float for a long time. Oatmeal flakes will float for a while, then sink to the bottom. Potatoes and carrots will sink. Lettuce and cabbage will float Regards.
Does plastic sink or float in oil?

Why do boats float and ships sink?

Does a pen float?
Whether a pen floats or sinks in water depends on its material. A plastic pen will typically float, while a metal pen will likely sink. The density of the material determines whether an object will float or sink in water.
Why do boats float but humans don't?
Actually, humans do float. It's just that some of your clothes weigh you down.For the reason on why boats float, it is because the water is denser than the boat filled with air. If you fill a boat with water, then it will sink.
Debbie was doing a science lab and she was instructed to decide whether a piece of plastic would float or sink without actually putting the plastic in the water. How could she do this?
Debbie can determine whether the piece of plastic will float or sink by comparing its density to that of water. If the density of the plastic is less than that of water (1 gram per cubic centimeter), it will float; if it is greater, it will sink. She can also refer to the material's known properties, as most types of plastic generally have a density less than water, indicating they typically float.
Will plastic float in water?
Some plastics will float in water and others will sink. It depends on the type of plastic and in particular it depends on the density of the plastic material. This property is used as a method for separating the different plastics sent for recycling. Polyethylene and Polypropylene, for example, will float in water while PVC and ABS will sink.
Do clothespins sink or float?
Clothespins typically float in water because they are made of lightweight wood or plastic. However, if the clothespin becomes saturated with water, it may eventually sink.
