Introduction:
Squeezing toothpaste out of a toothpaste tube is a common daily activity that we hardly ever pay attention to. However, there are several scientific principles behind this process that can be explained.

Effect of Force:
The force applied to the toothpaste tube causes toothpaste to come out of the tube. If we apply a small force to the toothpaste tube, only a small amount of toothpaste will come out. Conversely, if we apply a large force, more toothpaste will come out. This is because of the following:

Pressure:
When we apply force on the toothpaste tube, it creates pressure inside the tube. When this pressure is greater than the pressure outside of the tube, the toothpaste comes out. The pressure inside the tube is created due to the force applied on the toothpaste.

Vacuum effect:
When toothpaste is squeezed out of the tube, it creates a vacuum inside the tube. This vacuum is created due to the displacement of the toothpaste from the tube. The vacuum effect helps to bring out more toothpaste from the tube.

Conclusion:
In summary, the effect of force while squeezing out toothpaste from a toothpaste tube is due to the pressure and vacuum effect created by the force applied to the tube. The more force applied, the greater the pressure and vacuum effect, resulting in more toothpaste coming out of the tube. It is important to note that the force applied should be controlled to avoid wastage of toothpaste.
