There are many names for small sharp pins such as: Pins, Needles, etc. The one that is most likely is a tack. That is probably your answer, a tack.

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.
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 blunt pin has a larger surface area compared to a sharp pin, causing the pressure to be distributed over a larger area. This requires more force to penetrate the same material compared to a sharp pin, which concentrates the force over a smaller area.

Put a pin or something sharp in it
becoz it can easily pierce through anything...(when it is sharp)
To prick is to make a very small hole or wound with a sharp object such as a pin or a knife. 'Prick' as a noun is used as a nickname for penis.
A pin can pop a balloon because it has a very small, sharp point that can easily puncture the thin surface of the balloon. When the point of the pin comes into contact with the balloon, it creates a small hole through which the air inside the balloon can escape rapidly, causing the balloon to burst.
When a balloon is pierced with a pin, the sudden pressure from the sharp object creates a small tear in the balloon's thin material. This tear rapidly expands due to the high pressure inside the balloon, causing the balloon to burst.
The sharp end of a pin is called the "point." This is the part designed to penetrate materials, allowing the pin to serve its purpose in fastening or holding items together. The point is typically tapered to ensure ease of insertion and effectiveness in use.
