Im not sure but i think u shoukld hollow the middle
The main body of the pencil is made from soft wood which is naturally boyant, the pencil 'lead' is not lead at all but a much lighter substance called graphite. Your pencil is just not heavy enough to sink.
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
You can make a pencil float in the air by using powerful magnets. Place a magnet above and below the pencil to create a magnetic field that counteracts gravity and lifts the pencil. Be cautious when working with magnets to avoid any accidents or damage.
No
I can make a iron nail float. Simply melt some lead and the iron will float on top of the lead. Your question seems to be with regard to how do Boats float and the answer is Bouyancy. The Boat displaces a volume of water and if the weight of the displaced water is less than the weight of the boat, the boat will float.
pencil lead is not charcoal but rather graphite molded with clay and hardened
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
With wood and lead
Graphite is the mineral that is used to make pencil lead. It is a form of carbon that is known for its ability to make marks on paper.
first of all it depends on the type of pencil. Heavier pencils may sink bu tmost pencils will float.
Although they both still have the same basic elements (i.e. pencil and lead vs water), there is a physical state change that occurs when you freeze water to make ice. Sharpening/shaving down a pencil only results in a difference of shape and size. It's about the same as ripping paper vs burning paper. Also, freezing water to make ice is a reversible change (you can melt ice to turn it back into water) and shaving a pencil is an irreversible change (you can't sharpen a pencil and then put the pencil shavings back onto the pencil.)
Yes, adding salt to water increases its density, which can make some objects that would normally sink, like eggs, float. By altering the density of the water, the buoyant force exerted on the object can be increased to make it float.
