Check out the comments for Nuclear Grade 48-Millimeter-by-54.8-Meter Duct Tape, Slate Blue
When we found cracks in the containment structure, we used to have to shut the whole plant down; then there was a lot of hassle with the nuclear regulatory agency about structural integrity and environmental contamination. With this quality duct tape, that’s all in the past. Now, when we see a cracked or crumbling wall, we just bring out the tape. The slate blue blends right in. I do recommend that you use use double layers for openings near the reactor core.
But while the red duct tape has no reviews yet, 16% of those viewing it purchase Ghirardelli Chocolate Premium Hot Cocoa Mix, Double Chocolate, 16-Ounce Tins (Pack of 4), while buyers of the blue tape bought Gummi bears. What does that say about their psyches? Discuss.
