Figure 1![]() |
Equipment Setup:
Setup #1 Comments: In Figures 1 and 2 heavy polyester thread was set in front of the bullet to illustrate perfect immobility during 1/70,000 of a second. This stout thread was loosely held at both ends yet was stretched to about half its thickness to allow for the increased length at the point of impact. |
Figure 2![]() |
Equipment
Setup: Setup #1 Bullet: .22 calibre short Bullet Velocity: 1045 feet (318.5 m) per sec Presumed Displacement During Flash of 1/70,000 sec: 0.179 inch (.45 cm) Actual Displacement: Nil Comments: See Figure 1 comments above. If motion were continuous, the bullets and the thread in Figure's 1 and 2 would have streaked 0.178 inch (4.52 mm). Yet no streaking is present, suggesting that all the objects are, in fact, immobile. |
Figure 3![]() |
Equipment
Setup: Setup #1 Bullet: .303 calibre Bullet Velocity: 2725 feet (830.6 m) per sec Presumed Displacement During Flash of 1/70,000 sec: 0.46 inch (1.16 cm) Actual Displacement: Nil Comments: The .303 calibre bullet in Figure 3 was easiest to photograph because of its pointed shape. Though slight blurring appears due to compression of air in front, the bullet is fully discernable, and shows nowhere near the half inch of streaking that should be there. |
Figure 4![]() |
Equipment
Setup: Setup #1 Bullet: .220 calibre Swift Bullet Velocity: 4110 feet (1252.7 m) per sec Presumed Displacement During Flash of 1/70,000 sec: 0.70 inch (1.78 cm) Actual Displacement: Nil Comments: In Figure 4, this high-velocity bullet cut the thread on impact but did not at all disturb its two vertical ends. The lower end has not started to fall. This bullet was the most difficult to photograph because of front air compression. However, the front and back of the bullet are discernable and do not show the nearly 3/4" of streaking that should be visible. |
