Mr. R.’s World of Math

I could see Jackie was very upset about Pointy.
“I’m sure he’ll turn up after we clean for a while, I’m sure there’s a logical explanation,” I said, “Now everyone roll up your sleeping bags and put them away in the closet.”
The students began rolling their sleeping bags, and Jake walked over to the closet. He opened the closet door and turned around. He looked scared, then he whispered, “Everyone come over here.”
We all rushed to the closet to look, and we couldn’t believe what we saw.  Pointy was there and it appeared to be floating in mid-air in the closet.
“A ghost is holding Pointy! I’m getting out of here!” yelled Joe.
All the students ran to the other side of the room and stared back at the closet. The stuffie certainly looked as if it was floating, but when I reached in to grab it, it just dropped to the floor. 
“The ghost just dropped Pointy!” yelled Jenna. 
I picked up Pointy and it seemed as normal and fluffy as any other stuffie I’d ever held. 
“Why was it floating? What’s going on Mr. R.?” asked Jake. 
“I’m not sure, but I know it wasn’t a ghost.”
“How do you know,” asked Carlos. 
“Because there’s no such thing as ghosts!” I said. 
“Then how was Pointy floating, and what happened to our stuffies last night?” asked Zander. 
“I’m sure there’s some logical way to explain everything,” I said. 
“You always say there’s a logical way to explain everything,” said Jake, “But maybe this time there isn’t.”
Maybe Jake was right, maybe there was no logical explanation.
Later that morning, after the students went off to music class  I was sitting at my desk thinking of possible reasons for the events of the previous night. 

 If I thought of 681 possible explanations for why Pointy had floated, and only 152 of them were logical, how many were not logical?
