I recently purchased some rather expensive, supposedly invincible tires for my commute / touring bike. The Schwalbe Marathon Supremes are acclaimed as about the most indestructible tire out there, short of a couple truly massive things that really aren't much fun to ride on.
Now, if you ever found yourself asking, as I have, "Self, just what would it take to puncture one of these tough tires?" I can now provide an answer.
From the mailbag: Dragon Eggs - Thank you to Rebecca Zachau for this picture of Game of Thrones style dragon eggs made with the EggBot! They turned out beautifully.
