 So the people in this video took a model rocket motor and strapped it onto a little home made Lego car. They set it up out in their dead end street and counted down from ten. Once this thing lights off it takes a sharp right turn and just keeps going around in a circle until it comes back around and heads straight for the kid that launched it. It looks like it hits the launching pad box and then goes airborn in a corkscrew. Finally it lands back on the ground and shoots off up the street. I had to watch this thing over and over from the point where they light it off.
Watch this rocket car go crazy in this video. Source: Big-boys.com |
