Re: Unfold the Prism
But that would ruin the puzzle.
The point is that only some of the nets will form a prism when folded, and you need to figure out which.
Why did the vector cross the road?
It wanted to be normal.

Oh right, sorry.
Well, as this puzzle was sent in by someone else, there isn't a solutions page yet. The only way to get a solution is to solve it.

It's hard to visualize some of them, but good practice I suppose
