How can you change the shape of a paper clip?
Try it: Bend the sample to any shape and then heat it in hot water, with a heat gun, or with a lighter to experience the shape change. It is truly magic! The paper clip can be bent and heated many times, but it will start to “forget” its shape if it is mistreated or bent excessively.
How do you make paper clips Springs?
You could even make your own spring from a paper clip. Simply straighten out the clip, coil the wire around a pencil and voila! You have turned a paperclip into a spring. As simple as it sounds, bending the wire around the pencil and forming it into a spiral was done through a degree of energy.
Will paper clip float or sink?
It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface. The high surface tension helps the paper clip – with much higher density – float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
Why do paper clips not float?
You know that as paperclips are made out of metal they’re more dense than water, that’s why they normally sink.
What happen to paper clip when it bent?
When higher stresses are applied, permanent (plastic) deformation occurs. For example, when a paper clip is bent a large amount and then released, it will remain partially bent. This plastic deformation involves the breaking of bonds, often by the motion of dislocations.
Can you heat treat a paperclip?
Steel is a metal which is a combination of the elements iron and carbon. Not all steels can be heat treated. The steel has to have enough carbon in it before the chemistry that changes its properties can work its magic. A steel paper clip does not have enough carbon in it to be heat treatable.
How do you make a bottle cap car?
Steps
- Clean the plastic bottle. Take the label off the bottle.
- Drill the two holes into each side of the bottle.
- Find your axles.
- Gather four bottle caps.
- Paint the car and wheels.
- Place the axles into the plastic bottle.
- Drill a hole into the lid.
- Cut the top of the bottle to make a windshield.
