Burning through stuff!

Hi everyone!
I was wondering, if all the forum members pointed all their lasers at the same spot on a wall, what would happen? would the wall incinerate? :gun:
thanks,

What's the wall made of?

There would be a fire and popping. Several members have 20-60W CO2s and at least one has a ~1J or so Nd:YAG pulsed laser.
