This is a good demonstration of an idea for helping in the Gulf BP disaster. I don’t know if the blowout preventer could withstand the downward force exerted upon it by the plug however. But there are certainly adaptations of this idea that might work if the blowout preventer were removed from the equation. The main point though is that kids are engaging in logical thinking about the problem. At this very moment, I would be willing to bet that the complete solution to the BP oil disaster is already available. It has been thought of and put somewhere. For sure. It simply needs to be found now.
