We also had Blake do a cool demonstration for us this week. You may remember that the insulation inside our walls is cellulose, made out of treated recycled newspaper. Most regular homes use fiberglass insulation. You might be wondering, isn't newspaper flammable? Well, the cellulose is treated with borate, making it much less likely to burn than regular fiberglass. Blake did this demonstration to prove it -- watch what happens to the penny versus the cellulose:
The temperature got up to at least 800 degrees, and yet the cellulose did not catch on fire. And here is the same blowtorch being used on regular fiberglass insulation:
Very cool videos, y'all!
