Observations:  

The hardest part of the project was getting the timing right.  Once we got the delay time desired, then the project started rolling.  We had to adjust certain factors based on the results of our first shoot (Changing Camera Settings and Time Delay).                       

File 9- 10 shows that hypothesis one is clearly incorrect.  The eggs obviously explodes when impacted by a bullet.  In fact file 9 to file 11 to file 10 shows the progression of the egg explosion,  file 9 being the least amount of time since bullet impact and file 10 being the latest since bullet impact.  However from these pictures we can not conclude whether the bullet explodes the egg upon entry or exit.

File 20 and File 14 show the start of  the egg exploding. However we can not conclude that hypothesis (2) that the egg explodes upon the bullet's entry or hypothesis (3) that the egg explodes upon the bullet's exit because the bullet is not in the frame and therefore the bullet has already entered and exited.  We would need to obtain a picture of the bullet at the point of entry as well as a picture at the exact point of exit in order to determine whether the egg was exploded when the bullet entered or when the bullet was exiting.  We were not able to do this in the time span that was allotted because adjusting the delay for the flash unit takes precision and it is tedious work to find the exact point where the bullet enters or exits.

The Conclusions.
