“But,” said Oliver, “what is it made of?” He held a piece of tinsel up to just beyond his nose, squinting at it closely.

“Aluminum,” Sherlock said. “Coating polyvinyl chloride. We can look at it under a microscope.”

“Oh! Yes!”

“No,” John said sternly. “Not now. Now is not the science time, now we’re trimming the tree.”

“You know,” Sherlcok continued, “if we could get some vintage tinsel it would be even more instructive.”

“Why?” asked Oliver avidly.

“Because it used to contain lead. It was poisonous.”

Oliver’s eyes lit up.

John gave up on the idea of the tree.
