How can Santas reindeer fly?
It’s in their genes. After centuries of selective breeding and (more recently) bioengineering, the volumetic displacement of their lungs is of such a proportion that when filled with an appropriate mixture of helium, oxygen and nitrogen, they become buoyant. Pulling the sleigh becomes as easy for them as pulling a raft in water. How can Santa eat so much milk and cookies without bursting? Simple: He only takes one nibble at each house. The remainder is placed in his sleigh’s built-in food dehydrator, where it is preserved for future consumption. What is Santa’s sleigh made of?

This would make it very strong, lightweight, durable, and cold-resistant. Anecdotal evidence also supports this theory. “When going through the ionosphere, a sleigh made of this material would glow like a speck of bright red, a sight children and other rel
