**Title:** Experiment: Surviving a 20mm Cannon Shot with Body Armor
**Summary:**
* Hosts conduct an experiment using a one-of-a-kind, 20mm cannon (courtesy of Mark Serbu, Circle Firearms) to test the effectiveness of body armor.
* **Experiment 1:** A ballistic dummy with synthetic bones and organs, protected by 6 x Level 3 armor plates (courtesy of RTS Tactical), is shot. The bullet doesn't penetrate, but internal damage is observed, including shattered ribs.
* **Experiment 2:** The same dummy, now with only 1 armor plate, is shot again. This time, the bullet penetrates, causing extensive damage to the dummy and surrounding objects (watermelon, water).
* **Experiment 3:** A headshot is performed on the already damaged dummy, resulting in complete destruction of the head, with no brain matter remaining.
* The video concludes with acknowledgments to sponsors, including Ballistic Dummy Lab and RTS Tactical, and an announcement about the online education platform, Sonoran Desert Institute.
Here are the key facts extracted from the text, numbered and in short sentences:
**Equipment and Setup**
1. A 20mm cannon was used for the experiment, made by Circle Firearms (Mark Serbu).
2. The cannon shoots a 20mm round, compared to a 50 BMG shotgun shell for scale.
3. Armor plates were provided by RTS Tactical, rated to stop 7.62x39mm.
4. Six armor plates were initially lined up in front of a ballistic dummy.
5. A ballistic dummy with synthetic bones and organs was provided by Ballistic Dummy Labs.
**First Experiment (Multiple Armor Plates)**
6. The 20mm cannon was fired at the ballistic dummy with six armor plates in front.
7. The bullet did not penetrate the armor plates.
8. The dummy's internal organs were mostly intact after the shot.
9. The dummy's rib cage was shattered from the impact.
10. The spinal cord of the dummy remained intact.
**Second Experiment (Single Armor Plate)**
11. A single armor plate was used without back support for the second shot.
12. The 20mm bullet penetrated the single armor plate.
13. The bullet also went through a watermelon and caused significant damage.
**Third Experiment (Headshot)**
14. A headshot was performed on the dummy with the 20mm cannon.
15. The dummy's brain matter was completely disintegrated from the shot.
**Miscellaneous**
16. The online programs at Sonoran Desert Institute (SDI) cover various courses including gunsmithing and ballistics.
17. SDI ships tools and materials for hands-on practice to students' doors.
