- Jamie and Adam investigate the cliché that a quick thinking action hero can protect his fellow cast members from a grenade blast. Meanwhile in Diet Coke and Mentos - Exploding Stomach our intrepid trio test an Internet video with an outrageous claim.—Anonymous
- In this episode, three myths are tested: Will diving on a grenade save your buddies?, Does self-hypnosis work?, and Will a stomach explode if you eat diet coke and Mentos?
Diving on a Grenade was tested by using a human model made with ballistics gelatin. it was placed on top of the grenade and the grenade was remotely detonated. The damage from this explosion was compared to that of a baseline which was established with no inhibitions on the grenade. The second grenade myth within this that was tested, was will putting the grenade in a bucket of water downplay the grenade blast. This was Confirmed as the damage was considerably less than that of the baseline. The final myth within this that was tested was will a putting the grenade in a refrigerator help. This myth was Busted as parts of the refrigerator completely destroyed the plywood stand-ins on both the front and back although those on the side were relatively unharmed.
For Self-Hypnosis, Adam, Kari, and Grant each picked a self-hypnosis to try and prove. Adam was trying to get over his fear of bees, Grant was trying to cure himself of seasickness, and Kari was trying to change her eye color. For Adam, they used two methods of tracking his fear, the pulse rate, and a galvanometer. For Kari, they too, before and after pictures of her eyes. For Grant they used the "chunk chair" to simulate seasickness. The only difference for any of the tests was that it took a little bit longer for Grant to succumb to seasickness. This Busted the myth.
To test this myth, a pig stomach stood in for a human stomach. It was drained and an acid mixture was added to give the pH level of a stomach that had just eaten a bit of food. When it was loaded with Diet Coke and Mentos, nothing happened. Two possible reasons were named, the method of pouring the Diet Coke and the acid in the stomach. Further testing showed that it was the pouring method causing the lack of reaction. When they tried pouring it slower, the CO2 was still released too early, causing minimal reaction when the Mentos were added. In the end, the myth was Busted, but they still wanted to explode the stomach so they pumped it full of compressed air until it ruptured.
In Conclusion:
Diving on a Grenade - Confirmed
Self-Hypnosis - Busted
Stomach Explosion - Busted
