Wow, that is really cool. Is the 20 min time because the laser takes that long to heat the cork up? If so, could the burn time be reduced by using the laser out of a blu-ray player?

It's due to the fact that the laser takes a while to burn a spot on the cork, so the laser has to move slow enough such that the cork burns up. I think using a blu-ray laser would indeed reduce burn time
