How much power would it take to punch a hole in a piece of aluminum foil?
A. A Lot probably 10 Watts (10,000 mw) or more. A LASER’s light can only punch a hole in something if the “something” doesn’t reflect the light. Since a majority of the light hitting a piece of aluminum foil would be reflected and scattered, the little bit that was left would have to provide the “heat” and aluminum is a great heat dissipater.
