Hello, everyone! I bought HEPTYL The Most Dangerous Substance!? You will be surprised to see the title of a video. But I will prove in this video that HEPTYL is the most dangerous substance in the world. While reading the latest news, I noticed that many companies are starting to make more efficient and cheaper space rockets, some of them can even return to the ground and deliver cargo to orbit for less than 100 dollars per kilogram. Surprised?
Attention! This video shows dangerous experiments! Do not repeat the experiments shown in this video!
