Hi there.  I was watching mythbusters the other day and they were testing thermite on cotton sheets by painting it on then lighting it when it was dry.
I was wondering what did they use to get the thermite into a paste??
I was thinking maybe acetone or something but what they made on tv looked more like a paste that a solution.
Any ideas what they used?
i didnt even know it was possible to do that with thermite!!
