Cannon Procedure

Step One:

Obtain the materials:

1. Two label-less tennis ball cans                      

2. A pair of scissors

3. 18in of tape

Recommended Materials:
1. Protractor/Ruler
2. Permanent Marker

Step Two:                 

Get your design of your cannon onto

paper and properly label the measurements

Step Three:

       Construction of the cannon begins. We decided to cut the bottom part of        one of the tennis cans to create our base.

                                              Sammi and I begin to mark our length requirements cut out our cannon’s barrel 

 

Sammi begins to cut our base from the can

         

 Step Four:
        Start cutting the base making so that the barrel creates a 45° angle.

                                                I start to add the cut marks to make the groove in which the barrel will rest

                                                                                 

Step Five:

Mark the barrel with your measurements of the intended barrel length. We ended up making the cut half way from the base. The reason we did this was to allow the gas enough space to perform kinetic energy, thus creating pressure.

Step Six:

       Cutting the tennis ball can about 5in from the rim makes it easier for us to use a 45° angle. We believe that  45 ° angle will provide us with maximum distance.

                                                Trimming down our extra support will help us keep the cannon at a 45° angle

                                                                                      

Step 7: We decided to use the bottom part of the barrel as an

attachment toward the barrel’s base to give the cannon more stability.

Final Product

                                                

Conclusion:
As will many tests, hardly any of them are perfect, so here are our errors.

1.      The tape only seemed to want to stick to itself instead of the cannon

2.       Oddly shaped cut outs due to the amount of work needed to get rid of unnecessary material

3.      Measuring the angle of our cannon as two cylinders for a reference

4.     I believe our group has successfully made a cannon at the least, with a small enough barrel to allow Boyle’s Law to take effect.
