Week 5 : Lateral Thinking


Impossible Paper Trick

At home, I tried a couple of puzzles burt unfortunately, I failed.  So this is the solution of solving this.

Firstly, start with a paper rectangle, any size, 9" x 6" is fine. Make two right-angle cuts to the exact centre on one long side, at 3" and 6". Make one right-angle cut to the exact centre on the other long side at 4.5". Lay the sheet flat, fold over the central flap making a neat hinge and fold it back.

Lift the sheet by the two short sides, with the flap away from you, and twist one of the L-shaped ends 180 degrees (half a full turn).

Lay the sheet flat again, and fold the flap down both ways to create a hinge. The flap should now be erect, with half of the cut-away on each side - which looks like an impossible construction. This is what you show your audience. Ask them to explain it. 
Something like this
