Will a balloon pop if it is places on a bed of nails and pressure is applied?


If a balloon is placed on a bed of nails and a force is applied, then the balloon will burst.


Independent variable- Force applied to the balloon and number of nails

Dependent variable- Does the balloon burst?

14 inch by 14 in by .75 in plywood board x2
196 nails
4 rods (14 inches tall)
10 latex and 10 rubber balloons
Weights (1 lb, 5 lbs, 10 lbs; multiple of each weight)


Assembling the Board:
Using a pen and ruler, every one inch make a mark on one of the boards, these marks should be parallel to each other use a drill to place a nail at each one of the points made on the board, all nails will be used On the four corners drill a hole for a 14 inch rod facing the same way as the nails Using the drill again, make four holes in the corners of the other plywood board for the rods to slide through

Experiment Procedures:
Inflate the rubber balloons to 11 inches in diameter, all balloons should be plus or minus .2 of an inch in diameter Place rubber balloon on the middle of the bed of nails
Slide plywood board trough the rods to sandwich to balloon Record if the balloon pops or not and weight applied to balloon including the weight of the plywood board Repeat steps 2-4; add increasing amounts of weight every cycle Repeat steps 1-5 with latex balloons

Society as a whole has always had a thirst to expand their knowledge of the ever expanding universe around them. This drive has led man from living in caves and fighting every day to live; to living in the tallest manmade structures all over the world. The world of science has also advanced in leaps and bounds. In the area of physics it is an ever expanding field that encompasses many topics such as force, area and pressure which play an important role in everyday life.

Whenever two or more objects interact with each other using a push or a pull, this is called a force. “Force is defined as any of various factors that cause a body to change its speed, direction, or shape. It has both magnitude and direction. Contributions of force from different sources can be summed to give the net force at any given point.” (YourDictionary, 1996) A force can only be observed if there the objects are interacting with each other, when the contact concludes so does the force acting upon the two objects. Most forces between objects can be divided into contact forces and forces resulting from a distance. A contact force is when multiple objects are in contact with each other to exert a force. Some examples of contact forces are tensional forces, frictional forces, applied forces, air resistance forces, and normal forces. Objects that apply forces without physical contact, such as gravitational and magnetic forces, are distances forces. (Henderson, 2012)

Forces on objects can be measured using the formula F= ma, where F stands for force, m stands for the mass of the object, and a stands for acceleration of the same object. The quantity of force is measured in Newtons. “One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. Thus, the following unit equivalency can be stated: 1 Newton = 1 kg m/s2.” (Henderson, 2012) These forces are governed by Sir Isaac Newton’s First Law of Motion, which states that an object in motion will stay in motion and an object at rest will remain at rest until acted upon by an outside force. Newton’s Second Law of Motion states that for every action there is an equal and opposite reaction. (Nave, Force, 2005) Force is also a vector quantity, which is represented in diagrams by arrows, and the magnitude of the force is proportional to how big the arrow is.

On a two-dimensional plane the quantity that expresses...
