DR. FEYNMAN: This is a comment for Mr. Mulloy. I took this stuff that I got out of your seal and I put it in ice water, and I discovered that when you put some pressure on it for a while and then undo it it doesn't stretch back. It stays the same dimension. In other words, for a few seconds at least and more seconds than that, there is no resilience in this particular material when it is at a temperature of 32 degrees.
I believe that has some significance for our problem.
CHAIRMAN ROGERS: That is a matter we will consider, of course, at length in the session that we will hold on the weather, and I think it is an important point, which I'm sure Mr. Mulloy acknowledges and will comment on in a further session.
Now, if I may and if there are no further comments, I would like to ask Mr. Cook to come forward.
