You can buy my book Graphene 101 An Inventors guide to making graphene at the money will help my research. thanks. Okay, i was getting a lot of complaints about the audio - and yes it was terrible - so I finally got a new microphone and have re-recorded the audio fo rthis video. YouTube wont let you replace the audio on a video you have to upload a new video and as there are lots of good and interesting and useful comments on the original video I have uploaded this one as an alternative. I probably wont re-record the others as there a lot of problems like lipsync and messages and having too many copy vidoes around. But at least my videos from now on will have listenable-to sound!! sorry for the poor quality before.
