My data states 0.8 g/mL... Check it if you want.
A push pin is a type of inclined plane, where the sharp end acts as the wedge. By applying force to the head of the pin, the sharp end easily penetrates into surfaces.
A bobby pin can suspend in honey due to the honey's high viscosity creating resistance to the pin's movement through it. The honey's sticky properties also help to adhere the bobby pin to the surrounding honey molecules.
Edwin Moore invented the push pin in 1900 as a way to securely attach papers together without causing damage. The design of the push pin allowed it to easily pierce through paper and hold it in place, making it a convenient alternative to traditional pins or clips.
Because the pin is more dense than the water. Density and weight aren't the same thing. A feather, for example, has less density than the water so it would float.
Pressure is inversely proportional to area. A sharp pin has lesser area compared to a blunt pin. Therefore we require lesser pressure to push the pin with lesser area.Hence it's easier to push a sharp pin which has lesser area.
The safety pin has a pin that goes into the head of the pin, and you push the point in or out of the head of the pin.

a thumb tack has a flat circle top while a push pin has the tower like top.

yes it has them.
push pin
first push the pin to view trip miles. then to reset to zero push and hold the pin until you see zeros.
Pin
Pin you usually refers to pushing some one, as if to pin some one to the ground (push them to the ground).
